  • The Glass Revolution: How Intel and Samsung Are Shattering the Silicon Packaging Ceiling for AI Superchips

    The Glass Revolution: How Intel and Samsung Are Shattering the Silicon Packaging Ceiling for AI Superchips

    As of January 19, 2026, the semiconductor industry has officially entered what many are calling the "Glass Age." Driven by the insatiable appetite for compute power required by generative AI, the world’s leading chipmakers have begun a historic transition from organic substrates to glass. This shift is not merely an incremental upgrade; it represents a fundamental change in how the most powerful processors in the world are built, addressing a critical "warpage wall" that threatened to stall the development of next-generation AI hardware.

    The immediate significance of this development cannot be overstated. With the debut of the Intel (NASDAQ: INTC) Xeon 6+ "Clearwater Forest" at CES 2026, the industry has seen its first mass-produced chip utilizing a glass core substrate. This move signals the end of the decades-long dominance of Ajinomoto Build-up Film (ABF) in high-performance computing, providing the structural and thermal foundation necessary for "superchips" that now routinely exceed 1,000 watts of power consumption.

    The Technical Breakdown: Overcoming the "Warpage Wall"

    The move to glass is a response to the physical limitations of organic materials. Traditional ABF substrates, while reliable for decades, possess a Coefficient of Thermal Expansion (CTE) of roughly 15–17 ppm/°C. Silicon, by contrast, has a CTE of approximately 3 ppm/°C. As AI chips have grown larger and hotter, this mismatch has caused significant mechanical stress, leading to warped substrates and cracked solder bumps. Glass substrates solve this by offering a CTE of 3–5 ppm/°C, almost perfectly matching the silicon they support. This thermal stability allows for "reticle-busting" package sizes that can exceed 100mm x 100mm, accommodating dozens of chiplets and High Bandwidth Memory (HBM) stacks on a single, ultra-flat surface.

    Beyond physical stability, glass offers transformative electrical properties. Unlike organic substrates, glass allows for a 10x increase in routing density through Through-Glass Vias (TGVs) with a pitch of less than 10μm. This density is essential for the massive data-transfer rates required for AI training. Furthermore, glass significantly reduces signal loss—by as much as 40% compared to ABF—improving overall power efficiency for data movement by up to 50%. This capability is vital as hyperscale data centers struggle with the energy demands of LLM (Large Language Model) inference and training.

    Initial reactions from the AI research community have been overwhelmingly positive. Dr. Aris Gregorius, a lead packaging architect at the Silicon Valley Hardware Forum, noted that "glass is the only material capable of bridging the gap between current lithography limits and the multi-terawatt clusters of the future." Industry experts point out that while the transition is technically difficult, the success of Intel’s high-volume manufacturing (HVM) in Arizona proves that the manufacturing hurdles, such as glass brittleness and handling, have been successfully cleared.

    A New Competitive Front: Intel, Samsung, and the South Korean Alliance

    This technological shift has rearranged the competitive landscape of the semiconductor industry. Intel (NASDAQ: INTC) has secured a significant first-mover advantage, leveraging its advanced facility in Chandler, Arizona, to lead the charge. By integrating glass substrates into its Intel Foundry offerings, the company is positioning itself as the preferred partner for AI firms designing massive accelerators that traditional foundries struggle to package.

    However, the competition is fierce. Samsung Electronics (KRX: 005930) has adopted a "One Samsung" strategy, combining the glass-handling expertise of Samsung Display with the chipmaking prowess of its foundry division. Samsung Electro-Mechanics has successfully moved its pilot line in Sejong, South Korea, into full-scale validation, with mass production targets set for the second half of 2026. This consolidated approach allows Samsung to offer an end-to-end solution, specifically focusing on glass interposers for the upcoming HBM4 memory standard.

    Other major players are also making aggressive moves. Absolics, a subsidiary of SKC (KRX: 011790) backed by Applied Materials (NASDAQ: AMAT), has opened a state-of-the-art facility in Covington, Georgia. As of early 2026, Absolics is in the pre-qualification stage with AMD (NASDAQ: AMD) and Amazon (NASDAQ: AMZN) for custom AI hardware. Meanwhile, TSMC (NYSE: TSM) has accelerated its own Fan-Out Panel-Level Packaging (FO-PLP) on glass, partnering with Corning (NYSE: GLW) to develop specialized glass carriers that will eventually support its ubiquitous CoWoS (Chip-on-Wafer-on-Substrate) platform.

    Broader Significance: The Future of AI Infrastructure

    The industry-wide move to glass substrates is a clear indicator that the future of AI is no longer just about software algorithms, but about the physical limits of materials science. As we move deeper into 2026, the "Warpage Wall" has become the new frontier of Moore’s Law. By enabling larger, more densely packed chips, glass substrates allow for the continuation of performance scaling even as traditional transistor shrinking becomes prohibitively expensive and technically challenging.

    This development also has significant implications for sustainability. The 50% improvement in power efficiency for data movement provided by glass substrates is a rare "green" win in an industry often criticized for its massive carbon footprint. By reducing the energy lost to heat and signal degradation, glass-based chips allow data centers to maximize their compute-per-watt, a metric that has become the primary KPI for major cloud providers.

    There are, however, concerns regarding the supply chain. The transition requires a complete overhaul of packaging equipment and the development of new handling protocols for fragile glass panels. Some analysts worry that the initial high cost of glass substrates—currently 2-3 times that of ABF—could further widen the gap between tech giants who can afford the premium and smaller startups who may be priced out of the most advanced hardware.

    Looking Ahead: Rectangular Panels and the Cost Curve

    The next two to three years will likely be defined by the "Rectangular Revolution." While early glass substrates are being produced on 300mm round wafers, the industry is rapidly moving toward 600mm x 600mm rectangular panels. This transition is expected to drive costs down by 40-60% as the industry achieves the economies of scale necessary for mainstream adoption. Experts predict that by 2028, glass substrates will move beyond server-grade AI chips and into high-end consumer hardware, such as workstation-class laptops and gaming GPUs.

    Challenges remain, particularly in the area of yield management. Inspecting for micro-cracks in a transparent substrate requires entirely new metrology tools, and the industry is currently racing to standardize these processes. Furthermore, China's BOE (SZSE: 000725) is entering the market with its own mass production targets for mid-2026, suggesting that a global trade battle over glass substrate capacity is likely on the horizon.

    Summary: A Milestone in Computing History

    The shift to glass substrates marks one of the most significant milestones in semiconductor packaging since the introduction of the flip-chip in the 1960s. By solving the thermal and mechanical limitations of organic materials, Intel, Samsung, and their peers have unlocked a new path for AI superchips, ensuring that the hardware can keep pace with the exponential growth of AI models.

    As we look toward the coming months, the focus will shift to yield rates and the scaling of rectangular panel production. The "Glass Age" is no longer a futuristic concept; it is the current reality of the high-tech landscape, providing the literal foundation upon which the next decade of AI breakthroughs will be built.

  • The Glass Revolution: How Intel’s Breakthrough in Substrates is Powering the Next Leap in AI

    The Glass Revolution: How Intel’s Breakthrough in Substrates is Powering the Next Leap in AI

    As the artificial intelligence revolution accelerates, the industry has hit a physical barrier: traditional organic materials used to house the world’s most powerful chips are literally buckling under the pressure. Today, Intel (NASDAQ:INTC) has officially turned the page on that era, announcing the transition of its glass substrate technology into high-volume manufacturing (HVM). This development, centered at Intel’s advanced facility in Chandler, Arizona, represents one of the most significant shifts in semiconductor packaging in three decades, providing the structural foundation required for the 1,000-watt processors that will define the next phase of generative AI.

    The immediate significance of this move cannot be overstated. By replacing traditional organic resins with glass, Intel has dismantled the "warpage wall"—a phenomenon where massive AI chips expand and contract at different rates than their housing, leading to mechanical failure. As of early 2026, this breakthrough is no longer a research project; it is the cornerstone of Intel’s latest server processors and a critical service offering for its expanding foundry business, signaling a major strategic pivot as the company battles for dominance in the AI hardware landscape.

    The End of the "Warpage Wall": Technical Mastery of Glass

    Intel’s transition to glass substrates solves a looming crisis in chip design: the inability of organic materials like Ajinomoto Build-up Film (ABF) to stay flat and rigid as chip sizes grow. Modern AI accelerators, which often combine dozens of "chiplets" onto a single package, have become so large and hot that traditional substrates often warp or crack during the manufacturing process or under heavy thermal loads. Glass, by contrast, offers ultra-low flatness with sub-1nm surface roughness, providing a nearly perfect "optical" surface for lithography. This precision allows Intel to etch circuits with a 10x increase in interconnect density, enabling the massive I/O throughput required for trillion-parameter AI models.

    Technically, the advantages of glass are transformative. Intel’s 2026 implementation matches the Coefficient of Thermal Expansion (CTE) of silicon (3–5 ppm/°C), virtually eliminating the mechanical stress that leads to cracked solder bumps. Furthermore, glass is significantly stiffer than organic resins, supporting "reticle-busting" package sizes that exceed 100mm x 100mm. To connect the various layers of these massive chips, Intel utilizes high-speed laser-etched Through-Glass Vias (TGVs) with pitches of less than 10μm. This shift has resulted in a 40% reduction in signal loss and a 50% improvement in power efficiency for data movement between processing cores and High Bandwidth Memory (HBM4) stacks.

    The first commercial product to showcase this technology is the Xeon 6+ "Clearwater Forest" server processor, which debuted at CES 2026. Industry experts and researchers have reacted with overwhelming optimism, noting that while competitors are still in pilot stages, Intel’s move to high-volume manufacturing gives it a distinct "first-mover" advantage. "We are seeing the transition from the era of organic packaging to the era of materials science," noted one leading analyst. "Intel has essentially built a more stable, efficient skyscraper for silicon, allowing for vertical integration that was previously impossible."

    A Strategic Chess Move in the AI Foundry Wars

    The shift to glass substrates has major implications for the competitive dynamics between Intel, TSMC (NYSE:TSM), and Samsung (KRX:005930). Intel’s "foundry-first" strategy leverages its glass substrate lead to attract high-value clients who are hitting thermal limits with other providers. Reports indicate that hyperscale giants like Google (NASDAQ:GOOGL) and Microsoft (NASDAQ:MSFT) have already engaged Intel Foundry for custom AI silicon designs that require the extreme stability of glass. By offering glass packaging as a service, Intel is positioning itself as an essential partner for any company building "super-chips" for the data center.

    While Intel holds the current lead in volume production, its rivals are not sitting idle. TSMC has accelerated its "Rectangular Revolution," moving toward Fan-Out Panel-Level Packaging (FO-PLP) on glass to support the massive "Rubin" R100 GPU architecture from Nvidia (NASDAQ:NVDA). Meanwhile, Samsung has formed a "Triple Alliance" between its electronics and display divisions to fast-track its own glass interposers for HBM4 integration. However, Intel’s strategic move to license its glass patent portfolio to equipment and material partners, such as Corning (NYSE:GLW), suggests an attempt to set the global industry standard before its competitors can catch up.

    For AI chip designers like Nvidia and AMD (NASDAQ:AMD), the availability of glass substrates changes the roadmap for their upcoming products. Nvidia’s R100 series and AMD’s Instinct MI400 series—which reportedly uses glass substrates from merchant supplier Absolics—are designed to push the limits of power and performance. The strategic advantage for Intel lies in its vertical integration; by manufacturing both the chips and the substrates, Intel can optimize the entire stack for performance-per-watt, a metric that has become the gold standard in the AI era.

    Reimagining Moore’s Law for the AI Landscape

    In the broader context of the semiconductor industry, the adoption of glass substrates represents a fundamental shift in how we extend Moore’s Law. For decades, progress was defined by shrinking transistors. In 2026, progress is defined by "heterogeneous integration"—the ability to stitch together diverse chips into a single, cohesive unit. Glass is the "glue" that makes this possible at a massive scale. It allows engineers to move past the limitations of the "Power Wall," where the energy required to move data between chips becomes a bottleneck for performance.

    This development also addresses the increasing concern over environmental impact and energy consumption in AI data centers. By improving power efficiency for data movement by 50%, glass substrates directly contribute to more sustainable AI infrastructure. Furthermore, the move to larger, more complex packages allows for more powerful AI models to run on fewer physical servers, potentially slowing the footprint expansion of hyperscale facilities.

    However, the transition is not without challenges. The brittleness of glass compared to organic materials presents new hurdles for manufacturing yields and handling. While Intel’s Chandler facility has achieved high-volume readiness, maintaining those yields as package sizes scale to even more massive dimensions remains a concern. Comparison with previous milestones, such as the shift from aluminum to copper interconnects in the late 1990s, suggests that while the initial transition is difficult, the long-term benefits will redefine the ceiling for computing power for the next twenty years.

    The Future: From Glass to Light

    Looking ahead, the near-term roadmap for glass substrates involves scaling package sizes even further. Intel has already projected a move to 120x180mm packages by 2028, which would allow for the integration of even more HBM4 modules and specialized AI tiles on a single substrate. This will enable the creation of "super-accelerators" capable of training the first generation of multi-trillion parameter artificial general intelligence (AGI) models.

    Perhaps most exciting is the potential for glass to act as a conduit for light. Because glass is transparent and has superior optical properties, it is expected to facilitate the integration of Co-Packaged Optics (CPO) by the end of the decade. Experts predict that by 2030, copper wiring inside chip packages will be largely replaced by optical interconnects etched directly into the glass substrate. This would move data at the speed of light with virtually no heat generation, effectively solving the interconnect bottleneck once and for all.

    The challenges remaining are largely focused on the global supply chain. Establishing a robust ecosystem of glass suppliers and specialized laser-drilling equipment is essential for the entire industry to transition away from organic materials. As Intel, Samsung, and TSMC build out these capabilities, we expect to see a surge in demand for specialized materials and precision engineering tools, creating a new multi-billion dollar sub-sector within the semiconductor equipment market.

    A New Foundation for the Intelligence Age

    Intel’s successful push into high-volume manufacturing of glass substrates marks a definitive turning point in the history of computing. By solving the physical limitations of organic materials, Intel hasn't just improved a component; it has redesigned the foundation upon which all modern AI is built. This development ensures that the growth of AI compute will not be stifled by the "warpage wall" or thermal constraints, but will instead find new life in increasingly complex and efficient 3D architectures.

    As we move through 2026, the industry will be watching Intel’s yield rates and the adoption of its foundry services closely. The success of the "Clearwater Forest" Xeon processors will be the first real-world test of glass in the wild, and its performance will likely dictate the speed at which the rest of the industry follows. For now, Intel has reclaimed a crucial piece of the technological lead, proving that in the race for AI supremacy, the most important breakthrough may not be the silicon itself, but the glass that holds it together.

  • The Glass Revolution: How Intel and Samsung are Shattering the Thermal Limits of AI

    The Glass Revolution: How Intel and Samsung are Shattering the Thermal Limits of AI

    As the demand for generative AI pushes semiconductor design to its physical breaking point, a fundamental shift in materials science is taking hold across the industry. In a move that signals the end of the traditional plastic-based era, industry titans Intel and Samsung have transitioned into a high-stakes race to commercialize glass substrates. This "Glass Revolution" marks the most significant change in chip packaging in over three decades, promising to solve the crippling thermal and electrical bottlenecks that have begun to stall the progress of next-generation AI accelerators.

    The transition from organic materials, such as Ajinomoto Build-up Film (ABF), to glass cores is not merely an incremental upgrade; it is a necessary evolution for the age of the 1,000-watt GPU. As of January 2026, the industry has officially moved from laboratory prototypes to active pilot production, with major players betting that glass will be the key to maintaining the trajectory of Moore’s Law. By replacing the flexible, heat-sensitive organic resins of the past with ultra-rigid, thermally stable glass, manufacturers are now able to pack more processing power and high-bandwidth memory into a single package than ever before possible.

    Breaking the Warpage Wall: The Technical Leap to Glass

    The technical motivation for the shift to glass stems from a phenomenon known as the "warpage wall." Traditional organic substrates expand and contract at a much higher rate than the silicon chips they support. As AI chips like the latest NVIDIA (NASDAQ:NVDA) "Rubin" GPUs consume massive amounts of power, they generate intense heat, causing the organic substrate to warp and potentially crack the microscopic solder bumps that connect the chip to the board. Glass substrates, however, possess a Coefficient of Thermal Expansion (CTE) that nearly matches silicon. This allows for a 10x increase in interconnect density, enabling "sub-2 micrometer" line spacing that was previously impossible.

    Beyond thermal stability, glass offers superior flatness and rigidity, which is crucial for the ultra-precise lithography used in modern packaging. With glass, manufacturers can utilize Through-Glass Vias (TGV)—microscopic holes drilled with high-speed lasers—to create vertical electrical connections with far less signal loss than traditional copper-plated vias in organic material. This shift allows for an estimated 40% reduction in signal loss and a 50% improvement in power efficiency for data movement across the chip. This efficiency is vital for integrating HBM4 (High Bandwidth Memory) with processing cores, as it reduces the energy-per-bit required to move data, effectively cooling the entire system from the inside out.

    Furthermore, the industry is moving from circular 300mm wafers to large 600mm x 600mm rectangular glass panels. This "Rectangular Revolution" allows for "reticle-busting" package sizes. While organic substrates become unstable at sizes larger than 55mm, glass remains perfectly flat even at sizes exceeding 100mm. This capability allows companies like Intel (NASDAQ:INTC) to house dozens of chiplets—individual silicon components—on a single substrate, effectively creating a "system-on-package" that rivals the complexity of a mid-2000s motherboard but in the palm of a hand.

    The Global Power Struggle for Substrate Supremacy

    The competitive landscape for glass substrates has reached a fever pitch in early 2026, with Intel currently holding a slight technical lead. Intel’s dedicated glass substrate facility in Chandler, Arizona, has successfully transitioned to High-Volume Manufacturing (HVM) support. By focusing on the assembly and laser-drilling of glass cores sourced from specialized partners like Corning (NYSE:GLW), Intel is positioning its "foundry-first" model to attract major AI chip designers who are frustrated by the physical limits of traditional packaging. Intel’s 18A and 14A nodes are already leveraging this technology to power the Xeon 6+ "Clearwater Forest" processors.

    Samsung Electronics (KRX:000660) is pursuing a different, vertically integrated strategy often referred to as the "Triple Alliance." By combining the glass-processing expertise of Samsung Display, the design capabilities of Samsung Electronics, and the substrate manufacturing of Samsung Electro-Mechanics, the conglomerate aims to offer a "one-stop shop" for glass-based AI solutions. Samsung recently announced at CES 2026 that it expects full-scale mass production of glass substrates by the end of the year, specifically targeting the integration of its proprietary HBM4 memory modules directly onto glass interposers for custom AI ASIC clients.

    Not to be outdone, Taiwan Semiconductor Manufacturing Company (NYSE:TSM), or TSMC, has rapidly accelerated its "CoPoS" (Chip-on-Panel-on-Substrate) technology. Historically a proponent of silicon-based interposers (CoWoS), TSMC was forced to pivot toward glass panels to meet the demands of its largest customer, NVIDIA, for larger and more efficient AI clusters. TSMC is currently establishing a mini-production line at its AP7 facility in Chiayi, Taiwan. This move suggests that the industry's largest foundry recognizes glass as the indispensable foundation for the next five years of semiconductor growth, creating a strategic advantage for those who can master the yields of this difficult-to-handle material.

    A New Frontier for the AI Landscape

    The broader significance of the Glass Substrate Revolution lies in its ability to sustain the breakneck pace of AI development. As data centers grapple with skyrocketing energy costs and cooling requirements, the energy savings provided by glass-based packaging are no longer optional—they are a prerequisite for the survival of the industry. By reducing the power consumed by data movement between the processor and memory, glass substrates directly lower the Total Cost of Ownership (TCO) for AI giants like Meta (NASDAQ:META) and Google (NASDAQ:GOOGL), who are deploying hundreds of thousands of these chips simultaneously.

    This transition also marks a shift in the hierarchy of the semiconductor supply chain. For decades, packaging was considered a "back-end" process with lower margins than the actual chip fabrication. Now, with glass, packaging has become a "front-end" high-tech discipline that requires laser physics, advanced chemistry, and massive capital investment. The emergence of glass as a structural element in chips also opens the door for Silicon Photonics—the use of light instead of electricity to move data. Because glass is transparent, it is the natural medium for integrated optical I/O, which many experts believe will be the next major milestone after glass substrates, virtually eliminating latency in AI training clusters.

    However, the transition is not without its challenges. Glass is notoriously brittle, and handling 600mm panels without breakage requires entirely new robotic systems and cleanroom protocols. There are also concerns about the initial cost of glass-based chips, which are expected to carry a premium until yields reach the 90%+ levels seen in organic substrates. Despite these hurdles, the industry's total commitment to glass indicates that the benefits of performance and thermal management far outweigh the risks.

    The Road to 2030: What Comes Next?

    In the near term, expect to see the first wave of consumer "enthusiast" products featuring glass-integrated chips by early 2027, as the technology trickles down from the data center. While the primary focus is currently on massive AI accelerators, the benefits of glass—thinner profiles and better signal integrity—will eventually revolutionize high-end laptops and mobile devices. Experts predict that by 2028, glass substrates will be the standard for any processor with a Thermal Design Power (TDP) exceeding 150 watts.

    Looking further ahead, the integration of optical interconnects directly into the glass substrate is the next logical step. By 2030, we may see "all-optical" communication paths etched directly into the glass core of the chip, allowing for exascale computing on a single server rack. The current investments by Intel and Samsung are laying the foundational infrastructure for this future. The primary challenge remains scaling the supply chain to provide enough high-purity glass panels to meet a global demand that shows no signs of slowing.

    A Pivot Point in Silicon History

    The Glass Substrate Revolution will likely be remembered as the moment the semiconductor industry successfully decoupled performance from the physical constraints of organic materials. It is a triumph of materials science that has effectively reset the timer on the thermal limitations of chip design. As Intel and Samsung race to perfect their production lines, the resulting chips will provide the raw horsepower necessary to realize the next generation of artificial general intelligence and hyper-scale simulation.

    For investors and industry watchers, the coming months will be defined by "yield watch." The company that can first demonstrate consistent, high-volume production of glass substrates without the fragility issues of the past will likely secure a dominant position in the AI hardware market for the next decade. The "Glass Age" of computing has officially arrived, and with it, a new era of silicon potential.

  • Shattering the Warpage Wall: How Glass Substrates are Redefining the Future of AI Chips

    Shattering the Warpage Wall: How Glass Substrates are Redefining the Future of AI Chips

    The semiconductor industry has officially entered the "Glass Age." As of early 2026, the long-standing physical limits of organic packaging materials have finally collided with the insatiable thermal and processing demands of generative AI, sparking a massive industry-wide pivot. Leading the charge are South Korean tech giants Samsung Electro-Mechanics (KRX: 009150) and LG Innotek (KRX: 011070), both of whom have accelerated their roadmaps to replace traditional plastic-based substrates with high-precision glass cores.

    This transition is not merely an incremental upgrade; it is a fundamental architectural shift. Samsung Electro-Mechanics is currently on track to deliver its first commercial prototypes by the end of 2026, while LG Innotek has set a firm sights on 2028 for full-scale mass production. For the AI industry, which is currently struggling to scale hardware beyond the 1,000-watt threshold, glass substrates represent the "holy grail" of packaging—offering the structural integrity and electrical performance required to power the next generation of "super-chips."

    Breaking the "Warpage Wall" with Glass Precision

    At the heart of this shift is a phenomenon known as the "warpage wall." For decades, the industry has relied on Ajinomoto Build-up Film (ABF), an organic, plastic-like material, to connect silicon chips to circuit boards. However, as AI accelerators from companies like NVIDIA (NASDAQ: NVDA) and AMD (NASDAQ: AMD) grow larger and hotter, these organic materials have reached their breaking point. Because organic substrates have a significantly higher Coefficient of Thermal Expansion (CTE) than the silicon they support, they physically warp and bend under extreme heat. This deformation leads to "cracked micro-bumps"—microscopic failures in the electrical connections that render the entire chip useless.

    Glass substrates solve this by matching the CTE of silicon almost perfectly. By providing a substrate that remains ultra-flat even at temperatures exceeding those found in high-density data centers, manufacturers can build packages larger than 100mm x 100mm—a feat previously impossible with organic materials. Furthermore, glass allows for a "40% better signal integrity" profile, primarily through a dramatic reduction in signal loss. This efficiency enables data to move across the package with up to 50% lower power consumption, a critical metric for hyperscalers like Amazon (NASDAQ: AMZN) and Microsoft (NASDAQ: MSFT) who are battling rising energy costs in their AI infrastructures.

    The technical superiority of glass also extends to interconnect density. Unlike organic substrates that require mechanical drilling, glass uses laser-etched Through-Glass Vias (TGVs). This allows for a 10-fold increase in the number of vertical connections, enabling designers to pack dozens of High Bandwidth Memory (HBM) stacks directly around a GPU. Industry experts have described this as a "once-in-a-generation" leap that effectively bypasses the physical scaling limits that once threatened the post-Moore’s Law era.

    A Battle of Giants: Samsung vs. Intel vs. LG Innotek

    The race for glass supremacy has created a new competitive frontier among the world’s largest semiconductor players. Samsung Electro-Mechanics has utilized a "Triple Alliance" strategy, drawing on the glass-processing expertise of Samsung Display and the chip-making prowess of Samsung Electronics to fast-track its Sejong-based pilot line. Samsung CEO Chang Duck-hyun recently noted that 2026 will be the "defining year" for the commercialization of these "dream substrates," positioning the company to be a primary supplier for the next wave of AI hardware.

    However, they are not alone. Intel (NASDAQ: INTC), an early pioneer in the space, has already moved into high-volume manufacturing (HVM) at its Arizona facility, aiming to integrate glass cores into its 18A and 14A process nodes. Meanwhile, LG Innotek is playing a more calculated long-game. While their mass production target is 2028, LG Innotek CEO Moon Hyuk-soo has emphasized that the company is focusing on solving the industry's most nagging problem: glass brittleness. "Whoever solves the issue of glass cracking first will lead the market," Moon stated during a recent industry summit, highlighting LG’s focus on durability and yield over immediate speed-to-market.

    This competition is also drawing in traditional foundry leaders. TSMC (NYSE: TSM) has recently pivoted toward Fan-Out Panel-Level Packaging (FO-PLP) on glass to support future architectures like NVIDIA’s "Rubin" R100 GPUs. As these companies vie for dominance, the strategic advantage lies in who can most efficiently transition from 300mm circular wafers to massive 600mm x 600mm rectangular glass panels—a shift known as the "Rectangular Revolution" that promises to slash manufacturing costs while increasing usable area by over 80%.

    The Wider Significance: Enabling the 1,000-Watt AI Era

    The move to glass substrates is a direct response to the "energy wall" facing modern AI. As models grow more complex, the hardware required to train them has become increasingly power-hungry. Traditional packaging methods have become a bottleneck, both in terms of heat dissipation and the energy required just to move data between the processor and memory. By improving signal integrity and thermal management, glass substrates are essentially "widening the pipe" for AI computation, allowing for more performant chips that are simultaneously more energy-efficient.

    This shift also marks a broader trend toward "System-in-Package" (SiP) innovation. In the past, performance gains came primarily from shrinking transistors on the silicon itself. Today, as that process becomes exponentially more expensive and difficult, the industry is looking to the package—the "house" the chip lives in—to drive the next decade of performance. Glass is the foundation of this new house, enabling a modular "chiplet" approach where different types of processors and memory can be tiled together with near-zero latency.

    However, the transition is not without its risks. The primary concern remains the inherent fragility of glass. While it is thermally stable, it is susceptible to "micro-cracks" during the manufacturing process, which can lead to catastrophic yield losses. The industry's ability to develop automated handling equipment that can manage these ultra-thin glass panels at scale will determine how quickly the technology trickles down from high-end AI servers to consumer electronics.

    Future Developments and the Road to 2030

    Looking ahead, the roadmap for glass substrates extends far beyond 2026. While the immediate focus is on 1,000-watt AI accelerators for data centers, analysts expect the technology to migrate into high-end laptops and mobile devices by the end of the decade. By 2028, when LG Innotek enters the fray with its mass-production lines, we may see the first "all-glass" mobile processors, which could offer significant battery life improvements due to the reduced power required for internal data movement.

    The next two years will be characterized by rigorous testing and "qualification cycles." Hyperscalers are currently evaluating prototypes from Samsung and Absolics—a subsidiary of SKC (KRX: 011790)—to ensure these new substrates can survive the 24/7 high-heat environments of modern AI clusters. If these tests are successful, 2027 could see a massive "lift and shift" where glass becomes the standard for all high-performance computing (HPC) applications.

    Experts also predict that the rise of glass substrates will trigger a wave of mergers and acquisitions in the materials science sector. Traditional chemical suppliers will need to adapt to a world where glass-handling equipment and laser-via technologies are as essential as the silicon itself. The "cracking problem" remains the final technical hurdle, but with the combined R&D budgets of Samsung, LG, and Intel focused on the issue, a solution is widely expected before the 2028 production window.

    A New Foundation for Artificial Intelligence

    The shift toward glass substrates represents one of the most significant changes in semiconductor packaging in over twenty years. By solving the "warpage wall" and providing a 40% boost to signal integrity, glass is providing the physical foundation upon which the next decade of AI breakthroughs will be built. Samsung Electro-Mechanics’ aggressive 2026 timeline and LG Innotek’s specialized 2028 roadmap show that the industry's heaviest hitters are fully committed to this "Glass Age."

    As we move toward the end of 2026, the industry will be watching Samsung's pilot line in Sejong with intense scrutiny. Its success—or failure—to achieve high yields will serve as the first real-world test of whether glass can truly replace organic materials on a global scale.

  • The Glass Age: Why Intel and Samsung are Betting on Glass to Power 1,000-Watt AI Chips

    The Glass Age: Why Intel and Samsung are Betting on Glass to Power 1,000-Watt AI Chips

    As of January 2026, the semiconductor industry has officially entered what historians may one day call the "Glass Age." For decades, the foundation of chip packaging relied on organic resins, but the relentless pursuit of artificial intelligence has pushed these materials to their physical breaking point. With the latest generation of AI accelerators now demanding upwards of 1,000 watts of power, industry titans like Intel and Samsung have pivoted to glass substrates—a revolutionary shift that promises to solve the thermal and structural crises currently bottlenecking the world’s most powerful hardware.

    The transition is more than a mere material swap; it is a fundamental architectural redesign of how chips are built. By replacing traditional organic substrates with glass, manufacturers are overcoming the "warpage wall" that has plagued large-scale multi-die packages. This development is essential for the rollout of next-generation AI platforms, such as NVIDIA’s recently announced Rubin architecture, which requires the unprecedented stability and interconnect density that only glass can provide to manage its massive compute and memory footprint.

    Engineering the Transparent Revolution: TGVs and the Warpage Wall

    The technical shift to glass is necessitated by the extreme heat and physical size of modern AI "super-chips." Traditional organic substrates, typically made of Ajinomoto Build-up Film (ABF), have a high Coefficient of Thermal Expansion (CTE) that differs significantly from the silicon chips they support. As a 1,000-watt AI chip heats up, the organic substrate expands at a different rate than the silicon, causing the package to bend—a phenomenon known as the "warpage wall." Glass, however, can have its CTE precisely tuned to match silicon, reducing structural warpage by an estimated 70%. This allows for the creation of massive, ultra-flat packages exceeding 100mm x 100mm, which were previously impossible to manufacture with high yields.

    Beyond structural integrity, glass offers superior electrical properties. Through-Glass Vias (TGVs) are laser-etched into the substrate rather than mechanically drilled, allowing for a tenfold increase in routing density. This enables pitches of less than 10μm, allowing for significantly more data lanes between the GPU and its memory. Furthermore, glass's dielectric properties reduce signal transmission loss at high frequencies (10GHz+) by over 50%. This improved signal integrity means that data movement within the package consumes roughly half the power of traditional methods, a critical efficiency gain for data centers struggling with skyrocketing electricity demands.

    The industry is also moving away from circular 300mm wafers toward large 600mm x 600mm rectangular glass panels. This "Rectangular Revolution" increases area utilization from 57% to over 80%. By processing more chips simultaneously on a larger surface area, manufacturers can significantly increase throughput, helping to alleviate the global shortage of high-end AI silicon. Initial reactions from the research community suggest that glass substrates are the single most important advancement in semiconductor packaging since the introduction of CoWoS (Chip-on-Wafer-on-Substrate) nearly a decade ago.

    The Competitive Landscape: Intel’s Lead and Samsung’s Triple Alliance

    Intel Corporation (NASDAQ: INTC) has secured a significant first-mover advantage in this space. Following a billion-dollar investment in its Chandler, Arizona, facility, Intel is now in high-volume manufacturing (HVM) for glass substrates. At CES 2026, the company showcased its 18A (2nm-class) process node integrated with glass cores, powering the new Xeon 6+ "Clearwater Forest" server processors. By successfully commercializing glass substrates ahead of its rivals, Intel has positioned its Foundry Services as the premier destination for AI chip designers who need to package the world's most complex multi-die systems.

    Samsung Electronics (KRX: 005930) has responded with its "Triple Alliance" strategy, integrating its Electronics, Display, and Electro-Mechanics (SEMCO) divisions to fast-track its own glass substrate roadmap. By leveraging its world-class expertise in display glass, Samsung has brought a high-volume pilot line in Sejong, South Korea, into full operation as of early 2026. Samsung is specifically targeting the integration of HBM4 (High Bandwidth Memory) with glass interposers, aiming to provide a thermal solution for the memory-intensive needs of NVIDIA (NASDAQ: NVDA) and Advanced Micro Devices (NASDAQ: AMD).

    This shift creates a new competitive frontier for major AI labs and tech giants. Companies like NVIDIA and AMD are no longer just competing on transistor density; they are competing on packaging sophistication. NVIDIA's Rubin architecture, which entered production in early 2026, relies heavily on glass to maintain the integrity of its massive HBM4 arrays. Meanwhile, AMD has reportedly secured a deal with Absolics, a subsidiary of SKC (KRX: 011790), to utilize their Georgia-based glass substrate facility for the Instinct MI400 series. For these companies, glass substrates are not just an upgrade—they are the only way to keep the performance gains of "Moore’s Law 2.0" alive.

    A Wider Significance: Overcoming the Memory Wall and Optical Integration

    The adoption of glass substrates represents a pivotal moment in the broader AI landscape, signaling a move toward more integrated and efficient computing architectures. For years, the "memory wall"—the bottleneck caused by the slow transfer of data between processors and memory—has limited AI performance. Glass substrates enable much tighter integration of memory stacks, effectively doubling the bandwidth available to Large Language Models (LLMs). This allows for the training of even larger models with trillions of parameters, which were previously constrained by the physical limits of organic packaging.

    Furthermore, the transparency and flatness of glass open the door to Co-Packaged Optics (CPO). Unlike opaque organic materials, glass allows for the direct integration of optical interconnects within the chip package. This means that instead of using copper wires to move data, which generates heat and loses signal over distance, chips can use light. Experts believe this will eventually lead to a 50-90% reduction in the energy required for data movement, addressing one of the most significant environmental concerns regarding the growth of AI data centers.

    This milestone is comparable to the industry's shift from aluminum to copper interconnects in the late 1990s. It is a fundamental change in the "DNA" of the computer chip. However, the transition is not without its challenges. The current cost of glass substrates remains three to five times higher than organic alternatives, and the fragility of glass during the manufacturing process requires entirely new handling equipment. Despite these hurdles, the performance necessity of 1,000-watt chips has made the "Glass Age" an inevitability rather than an option.

    The Horizon: HBM4 and the Path to 2030

    Looking ahead, the next two to three years will see glass substrates move from high-end AI accelerators into more mainstream high-performance computing (HPC) and eventually premium consumer electronics. By 2027, it is expected that HBM4 will be the standard memory paired with glass-based packages, providing the massive throughput required for real-time generative video and complex scientific simulations. As manufacturing processes mature and yields improve, analysts predict that the cost premium of glass will drop by 40-60% by the end of the decade, making it the standard for all data center silicon.

    The long-term potential for optical computing remains the most exciting frontier. With glass substrates as the foundation, we may see the first truly hybrid electronic-photonic processors by 2030. These chips would use electricity for logic and light for communication, potentially breaking the power-law constraints that have slowed the advancement of traditional silicon. The primary challenge remains the development of standardized "glass-ready" design tools for chip architects, a task currently being tackled by major EDA (Electronic Design Automation) firms.

    Conclusion: A New Foundation for Intelligence

    The shift to glass substrates marks the end of the organic era and the beginning of a more resilient, efficient, and dense future for semiconductor packaging. By solving the critical issues of thermal expansion and signal loss, Intel, Samsung, and their partners have cleared the path for the 1,000-watt chips that will power the next decade of AI breakthroughs. This development is a testament to the industry's ability to innovate its way out of physical constraints, ensuring that the hardware can keep pace with the exponential growth of AI software.

    As we move through 2026, the industry will be watching the ramp-up of Intel’s 18A production and Samsung’s HBM4 integration closely. The success of these programs will determine the pace at which the next generation of AI models can be deployed. While the "Glass Age" is still in its early stages, its significance in AI history is already clear: it is the foundation upon which the future of artificial intelligence will be built.

  • The Glass Revolution: Why Intel and SKC are Abandoning Organic Materials for the Next Generation of AI

    The Glass Revolution: Why Intel and SKC are Abandoning Organic Materials for the Next Generation of AI

    The foundation of artificial intelligence is no longer just code and silicon; it is increasingly becoming glass. As of January 2026, the semiconductor industry has reached a pivotal turning point, officially transitioning away from traditional organic substrates like Ajinomoto Build-up Film (ABF) in favor of glass substrates. This shift, led by pioneers like Intel (NASDAQ: INTC) and SKC (KRX: 011790) through its subsidiary Absolics, marks the end of the "warpage wall" that has plagued high-heat AI chips for years.

    The immediate significance of this transition cannot be overstated. As AI accelerators from NVIDIA (NASDAQ: NVDA) and AMD (NASDAQ: AMD) push toward and beyond the 1,000-watt power envelope, traditional organic materials have proven too flexible and thermally unstable to support the massive, multi-die "super-chips" required for generative AI. Glass substrates provide the structural integrity and thermal precision necessary to pack trillions of transistors and dozens of High Bandwidth Memory (HBM) stacks into a single, cohesive package, effectively setting the stage for the next decade of AI hardware scaling.

    The Technical Edge: Solving the Warpage Wall

    The move to glass is driven by fundamental physics. Traditional organic substrates are essentially high-tech plastics that expand and contract at different rates than the silicon chips they support. This "Coefficient of Thermal Expansion" (CTE) mismatch causes chips to warp as they heat up, leading to cracked micro-bumps and signal failure. Glass, however, has a CTE that closely matches silicon (3–5 ppm/°C), ensuring that even under the extreme 100°C+ temperatures of an AI data center, the substrate remains perfectly flat.

    Technically, glass offers a level of precision that organic materials cannot match. While ABF-based substrates rely on mechanical drilling for "vias" (the vertical connections between layers), glass utilizes laser-etched Through-Glass Vias (TGV). This allows for an interconnect density nearly ten times higher than previous technologies, with pitches shrinking from 100μm to less than 10μm. Furthermore, glass boasts sub-1nm surface roughness, providing an ultra-flat canvas that improves lithography focus and allows for the etching of much finer circuits.

    This transition also addresses power efficiency. Glass has approximately 50% lower dielectric loss than organic materials, meaning less energy is wasted as heat when data moves between the GPU and its memory. For the research community, this means AI models can be trained on hardware that is not only faster but significantly more energy-efficient, a critical factor as global data center power consumption continues to skyrocket in 2026.

    Market Positioning: Intel, SKC, and the Battle for Packaging Supremacy

    Intel has positioned itself as the clear leader in this space, having invested over $1 billion in its commercial-grade glass substrate pilot line in Chandler, Arizona. By January 2026, this facility is actively producing glass cores for Intel’s 18A and 14A process nodes. Intel’s strategy is one of vertical integration; by controlling the substrate production in-house, Intel Foundry aims to attract "hyperscalers" like Google and Microsoft who are designing custom AI silicon and require the highest possible yields for their massive chip designs.

    Meanwhile, SKC’s subsidiary, Absolics—backed by Applied Materials (NASDAQ: AMAT)—has become the primary merchant supplier for the rest of the industry. Their $600 million facility in Covington, Georgia, reached a major milestone in late 2025 and is now ramping up to produce 20,000 sheets per month. Absolics has already secured high-profile partnerships with AMD and Amazon Web Services (AWS). For AMD, the use of Absolics' glass substrates in its Instinct MI400 series provides a strategic advantage, allowing them to offer higher memory bandwidth and better thermal management than competitors still reliant on older packaging techniques.

    Samsung (KRX: 005930) has also entered the fray with its "Triple Alliance" strategy, coordinating between its electronics, display, and electro-mechanics divisions. At CES 2026, Samsung announced that its high-volume pilot line in Sejong, South Korea, is ready for mass production by the end of the year. This competitive pressure is forcing a rapid evolution in the supply chain, as even TSMC (NYSE: TSM) has begun sampling glass-based panels to ensure it can support NVIDIA’s upcoming "Rubin" R100 GPUs, which are expected to be the first major consumer of glass-integrated packaging at scale.

    A Broader Shift in the AI Landscape

    The adoption of glass substrates fits into a broader trend toward "Panel-Level Packaging" (PLP). For decades, chips were packaged on circular silicon wafers. Glass allows for large, rectangular panels that can fit significantly more chips per batch, dramatically increasing manufacturing throughput. This transition is reminiscent of the industry’s move from 200mm to 300mm wafers, but with even greater implications for the physical size of AI processors.

    However, this shift is not without concerns. The transition to glass requires a complete overhaul of the back-end assembly process. Glass is brittle, and handling large, thin sheets of it in a high-speed manufacturing environment presents significant breakage risks. Industry experts have compared this milestone to the introduction of Extreme Ultraviolet (EUV) lithography—a necessary but painful transition that separates the leaders from the laggards in the semiconductor race.

    Furthermore, the move to glass is a key enabler for HBM4, the next generation of high-bandwidth memory. As memory stacks grow taller and more numerous, the substrate must be strong enough to support the weight and heat of 12 or 16 HBM cubes surrounding a central processor. Without glass, the "super-chips" envisioned for the 2027–2030 era would simply be impossible to manufacture with reliable yields.

    Future Horizons: Co-Packaged Optics and Beyond

    Looking ahead, the roadmap for glass substrates extends far beyond simple structural support. By 2027, experts predict the integration of Co-Packaged Optics (CPO) directly onto glass substrates. Because glass is transparent and can be manufactured with high optical clarity, it is the ideal medium for routing light signals (photons) instead of electrical signals (electrons) between chips. This would effectively eliminate the "memory wall," allowing for near-instantaneous communication between GPUs in a massive AI cluster.

    The near-term challenge remains yield optimization. While Intel and Absolics have proven the technology in pilot lines, scaling to millions of units per month will require further refinements in laser-drilling speed and glass-handling robotics. As we move into the latter half of 2026, the industry will be watching closely to see if glass-packaged chips can maintain their performance advantages without a significant increase in manufacturing costs.

    Conclusion: The New Standard for AI

    The shift to glass substrates represents one of the most significant architectural changes in semiconductor packaging history. By solving the dual challenges of flatness and thermal stability, Intel, SKC, and Samsung have provided the industry with a new foundation upon which the next generation of AI can be built. The "warpage wall" has been dismantled, replaced by a transparent, ultra-flat medium that enables the 1,000-watt processors of tomorrow.

    As we move through 2026, the primary metric for success will be how quickly these companies can scale production to meet the insatiable demand for AI compute. With NVIDIA’s Rubin architecture and AMD’s MI400 series on the horizon, the "Glass Revolution" is no longer a future prospect—it is the current reality of the AI hardware market. Investors and tech enthusiasts should watch for the first third-party benchmarks of these glass-packaged chips in the coming months, as they will likely set new records for both performance and efficiency.

  • The Glass Ceiling Shatters: How Glass Substrates are Redefining the Future of AI Accelerators

    The Glass Ceiling Shatters: How Glass Substrates are Redefining the Future of AI Accelerators

    As of early 2026, the semiconductor industry has reached a pivotal inflection point in the race to sustain the generative AI revolution. The traditional organic materials that have housed microchips for decades have officially hit a "warpage wall," threatening to stall the development of increasingly massive AI accelerators. In response, a high-stakes transition to glass substrates has moved from experimental laboratories to the forefront of commercial manufacturing, marking the most significant shift in chip packaging technology in over twenty years.

    This migration is not merely an incremental upgrade; it is a fundamental re-engineering of how silicon interacts with the physical world. By replacing organic resin with ultra-thin, high-strength glass, industry titans are enabling a 10x increase in interconnect density, allowing for the creation of "super-chips" that were previously impossible to manufacture. With Intel (NASDAQ: INTC), Samsung (KRX: 005930), and TSMC (NYSE: TSM) all racing to deploy glass-based solutions by 2026 and 2027, the battle for AI dominance has moved from the transistor level to the very foundation of the package.

    The Technical Breakthrough: Overcoming the Warpage Wall

    For years, the industry relied on Ajinomoto Build-up Film (ABF), an organic resin, to create the substrates that connect chips to circuit boards. however, as AI accelerators like those from NVIDIA (NASDAQ: NVDA) and AMD (NASDAQ: AMD) have grown larger and more power-hungry—often exceeding 1,000 watts of thermal design power—ABF has reached its physical limit. The primary culprit is the "warpage wall," a phenomenon caused by the mismatch in the Coefficient of Thermal Expansion (CTE) between silicon and organic materials. As these massive chips heat up and cool down, the organic substrate expands and contracts at a different rate than the silicon, causing the entire package to warp. This warping leads to cracked connections and "micro-bump" failures, effectively capping the size and complexity of next-generation AI hardware.

    Glass substrates solve this dilemma by offering a CTE that nearly matches silicon, providing unparalleled dimensional stability even at temperatures reaching 500°C. Beyond structural integrity, glass enables a massive leap in interconnect density through the use of Through-Glass Vias (TGVs). Unlike organic substrates, which require mechanical drilling that limits how closely connections can be spaced, glass can be etched with high-precision lasers. This allows for an interconnect pitch of less than 10 micrometers—a 10x improvement over the 100-micrometer pitch common in organic materials. This density is critical for the ultra-high-bandwidth memory (HBM4) and multi-die architectures required to train the next generation of Large Language Models (LLMs).

    Furthermore, glass provides superior electrical properties, reducing signal loss by up to 40% and cutting the power required for data movement by half. In an era where data center energy consumption is a global concern, the efficiency gains of glass are as valuable as its performance metrics. Initial reactions from the research community have been overwhelmingly positive, with experts noting that glass allows the industry to treat the entire package as a single, massive "system-on-wafer," effectively extending the life of Moore's Law through advanced packaging rather than just transistor scaling.

    The Corporate Race: Intel, Samsung, and the Triple Alliance

    The competition to bring glass substrates to market has ignited a fierce rivalry between the world’s leading foundries. Intel has taken an early lead, leveraging over a decade of research to establish a $1 billion commercial-grade pilot line in Chandler, Arizona. As of January 2026, Intel’s Chandler facility is actively producing glass cores for high-volume customers. This head start has allowed Intel Foundry to position glass packaging as a flagship differentiator, attracting cloud service providers who are designing custom AI silicon and need the thermal resilience that only glass can provide.

    Samsung has responded by forming a "Triple Alliance" that spans its most powerful divisions: Samsung Electronics, Samsung Display, and Samsung Electro-Mechanics. By repurposing the glass-processing expertise from its world-leading OLED and LCD businesses, Samsung has bypassed many of the supply chain hurdles that have slowed others. At the start of 2026, Samsung’s Sejong pilot line completed its final verification phase, with the company announcing at CES 2026 that it is on track for full-scale mass production by the end of the year. This integrated approach allows Samsung to offer an end-to-end glass solution, from the raw glass core to the final integrated AI package.

    Meanwhile, TSMC has pivoted toward a "rectangular revolution" known as Fan-Out Panel-Level Packaging (FO-PLP) on glass. By moving from traditional circular wafers to 600mm x 600mm rectangular glass panels, TSMC aims to increase area utilization from roughly 57% to over 80%, significantly lowering the cost of large-scale AI chips. TSMC’s branding for this effort, CoPoS (Chip-on-Panel-on-Substrate), is expected to be the successor to its industry-standard CoWoS technology. While TSMC is currently stabilizing yields on smaller 300mm panels at its Chiayi facility, the company is widely expected to ramp to full panel-level production by 2027, ensuring it remains the primary manufacturer for high-volume players like NVIDIA.

    Broader Significance: The Package is the New Transistor

    The shift to glass substrates represents a fundamental change in the AI landscape, signaling that the "package" has become as important as the "chip" itself. For the past decade, AI performance gains were largely driven by making transistors smaller. However, as we approach the physical limits of atomic-scale manufacturing, the bottleneck has shifted to how those transistors communicate and stay cool. Glass substrates remove this bottleneck, enabling the creation of 1-trillion-transistor packages that can span the size of an entire palm, a feat that would have been physically impossible with organic materials.

    This development also has profound implications for the geography of semiconductor manufacturing. Intel’s investment in Arizona and the emergence of Absolics (a subsidiary of SKC) in Georgia, USA, suggest that advanced packaging could become a cornerstone of the "onshoring" movement. By bringing high-end glass substrate production to the United States, these companies are shortening the supply chain for American AI giants like Microsoft (NASDAQ: MSFT) and Google (NASDAQ: GOOGL), who are increasingly reliant on custom-designed accelerators to run their massive AI workloads.

    However, the transition is not without its challenges. The fragility of glass during the manufacturing process remains a concern, requiring entirely new handling equipment and cleanroom protocols. Critics also point to the high initial cost of glass substrates, which may limit their use to the most expensive AI and high-performance computing (HPC) chips for the next several years. Despite these hurdles, the industry consensus is clear: without glass, the thermal and physical scaling of AI hardware would have hit a dead end.

    Future Horizons: Toward Optical Interconnects and 2027 Scaling

    Looking ahead, the roadmap for glass substrates extends far beyond simple structural support. By 2027, the industry expects to see the first wave of "Second Generation" glass packages that integrate silicon photonics directly into the substrate. Because glass is transparent, it allows for the seamless integration of optical interconnects, enabling chips to communicate using light rather than electricity. This would theoretically provide another order-of-magnitude jump in data transfer speeds while further reducing power consumption, a holy grail for the next decade of AI development.

    AMD is already in advanced evaluation phases for its MI400 series accelerators, which are rumored to be among the first to fully utilize these glass-integrated optical paths. As the technology matures, we can expect to see glass substrates trickle down from high-end data centers into high-performance consumer electronics, such as workstations for AI researchers and creators. The long-term vision is a modular "chiplet" ecosystem where different components from different manufacturers can be tiled onto a single glass substrate with near-zero latency between them.

    The primary challenge moving forward will be achieving the yields necessary for true mass-market adoption. While pilot lines are operational in early 2026, scaling to millions of units per month will require a robust global supply chain for high-purity glass and specialized laser-drilling equipment. Experts predict that 2026 will be the "year of the pilot," with 2027 serving as the true breakout year for glass-core AI hardware.

    A New Era for AI Infrastructure

    The industry-wide shift to glass substrates marks the end of the organic era for high-performance computing. By shattering the warpage wall and enabling a 10x leap in interconnect density, glass has provided the physical foundation necessary for the next decade of AI breakthroughs. Whether it is Intel's first-mover advantage in Arizona, Samsung's triple-division alliance, or TSMC's rectangular panel efficiency, the leaders of the semiconductor world have all placed their bets on glass.

    As we move through 2026, the success of these pilot lines will determine which companies lead the next phase of the AI gold rush. For investors and tech enthusiasts, the key metrics to watch will be the yield rates of these new facilities and the performance benchmarks of the first glass-backed AI accelerators hitting the market in the second half of the year. The transition to glass is more than a material change; it is the moment the semiconductor industry stopped building bigger chips and started building better systems.

  • Breaking the Warpage Wall: The Semiconductor Industry Pivots to Glass Substrates for the Next Era of AI

    Breaking the Warpage Wall: The Semiconductor Industry Pivots to Glass Substrates for the Next Era of AI

    As of January 7, 2026, the global semiconductor industry has reached a critical inflection point. For decades, organic materials like Ajinomoto Build-up Film (ABF) served as the foundation for chip packaging, but the insatiable power and size requirements of modern Artificial Intelligence (AI) have finally pushed these materials to their physical limits. In a move that analysts are calling a "once-in-a-generation" shift, industry titans are transitioning to glass substrates—a breakthrough that promises to unlock a new level of performance for the massive, multi-die packages required for next-generation AI accelerators.

    The immediate significance of this development cannot be overstated. With AI chips now exceeding 1,000 watts of thermal design power (TDP) and reaching physical dimensions that would cause traditional organic substrates to warp or crack, glass provides the structural integrity and electrical precision necessary to keep Moore’s Law alive. This transition is not merely an incremental upgrade; it is a fundamental re-engineering of how the world's most powerful chips are built, enabling a 10x increase in interconnect density and a 40% reduction in signal loss.

    The Technical Leap: From Organic Polymers to Precision Glass

    The shift to glass substrates is driven by the failure of organic materials to scale alongside the "chiplet" revolution. Traditional organic substrates are prone to "warpage"—the physical deforming of the material under high temperatures—which limits the size of a chip package to roughly 55mm x 55mm. As AI GPUs from companies like NVIDIA (NASDAQ: NVDA) and AMD (NASDAQ: AMD) grow to 100mm x 100mm and beyond, the industry has hit what experts call the "warpage wall." Glass, with its superior thermal stability, remains flat even at temperatures exceeding 500°C, matching the coefficient of thermal expansion of silicon and preventing the catastrophic mechanical failures seen in organic designs.

    Technically, the most significant advancement lies in Through-Glass Vias (TGVs). Unlike the mechanical drilling used for organic substrates, TGVs are etched using high-precision lasers, allowing for an interconnect pitch of less than 10 micrometers—a 10x improvement over the 100-micrometer pitch common in organic materials. This density allows for significantly more "tiles" or chiplets to be packed into a single package, facilitating the massive memory bandwidth required for Large Language Models (LLMs). Furthermore, glass's ultra-low dielectric loss improves signal integrity by nearly 40%, which translates to a power consumption reduction of up to 50% for data movement within the chip.

    Initial reactions from the AI research community and industry experts have been overwhelmingly positive. At the recent CES 2026 "First Look" event, analysts noted that glass substrates are the "critical enabler" for 2.5D and 3D packaging. While organic substrates still dominate mainstream consumer electronics, the high-performance computing (HPC) sector has reached a consensus: without glass, the physical size of AI clusters would be capped by the mechanical limits of plastic, effectively stalling AI hardware progress.

    Competitive Landscapes: Intel, Samsung, and the Race for Packaging Dominance

    The transition to glass has sparked a fierce competition among the world’s leading foundries and IDMs. Intel Corporation (NASDAQ: INTC) has emerged as an early technical pioneer, having officially reached High-Volume Manufacturing (HVM) for its 18A node as of early 2026. Intel’s dedicated glass substrate facility in Chandler, Arizona, has successfully transitioned from pilot phases to supporting commercial-grade packaging. By offering glass-based solutions to its foundry customers, Intel is positioning itself as a formidable alternative to TSMC (NYSE: TSM), specifically targeting NVIDIA and AMD's high-end business.

    Samsung (KRX: 005930) is not far behind. Samsung Electro-Mechanics (SEMCO) has fast-tracked its "dream substrate" program, completing verification of its high-volume pilot line in Sejong, South Korea, in late 2025. Samsung announced at CES 2026 that it is on track for full-scale mass production by the end of the year. To bolster its competitive edge, Samsung has formed a "triple alliance" between its substrate, electronics, and display divisions, leveraging its expertise in glass processing from the smartphone and TV industries.

    Meanwhile, TSMC has been forced to pivot. Originally focused on silicon interposers (CoWoS), the Taiwanese giant revived its glass substrate R&D in late 2024 under intense pressure from its primary customer, NVIDIA. As of January 2026, TSMC is aggressively pursuing Fan-Out Panel-Level Packaging (FO-PLP) on glass. This "Rectangular Revolution" involves moving from 300mm circular silicon wafers to large 600mm x 600mm rectangular glass panels. This shift increases area utilization from 57% to over 80%, drastically reducing the "AI chip bottleneck" by allowing more chips to be packaged simultaneously and at a lower cost per unit.

    Wider Significance: Moore’s Law and the Energy Efficiency Frontier

    The adoption of glass substrates fits into a broader trend known as "More than Moore," where performance gains are achieved through advanced packaging rather than just transistor shrinking. As it becomes increasingly difficult and expensive to shrink transistors below the 2nm threshold, the ability to package multiple specialized chiplets together with high-speed, low-power interconnects becomes the primary driver of computing power. Glass is the medium that makes this "Lego-style" chip building possible at the scale required for future AI.

    Beyond raw performance, the move to glass has profound implications for energy efficiency. Data centers currently consume a significant portion of global electricity, with a large percentage of that energy spent moving data between processors and memory. By reducing signal attenuation and cutting power consumption by up to 50%, glass substrates offer a rare opportunity to improve the sustainability of AI infrastructure. This is particularly relevant as global regulators begin to scrutinize the carbon footprint of massive AI training clusters.

    However, the transition is not without concerns. Glass is inherently brittle, and manufacturers are currently grappling with breakage rates that are 5-10% higher than organic alternatives. This has necessitated entirely new automated handling systems and equipment from vendors like Applied Materials (NASDAQ: AMAT) and Coherent (NYSE: COHR). Furthermore, initial mass production yields are hovering between 70% and 75%, trailing the 90%+ maturity of organic substrates, leading to a temporary cost premium for the first generation of glass-packaged chips.

    Future Horizons: Optical I/O and the 2030 Roadmap

    Looking ahead, the near-term focus will be on stabilizing yields and standardizing panel sizes to bring down costs. Experts predict that while glass substrates currently carry a 3x to 5x cost premium, aggressive cost reduction roadmaps will see prices decline by 40-60% by 2030 as manufacturing scales. The first commercial products to feature full glass core integration are expected to hit the market in late 2026 and early 2027, likely appearing in NVIDIA’s "Rubin" architecture and AMD’s MI400 series accelerators.

    The long-term potential of glass extends into the realm of Silicon Photonics. Because glass is transparent and thermally stable, it is being positioned as the primary medium for Co-Packaged Optics (CPO). In this future scenario, data will be moved via light rather than electricity, virtually eliminating latency and power loss in AI clusters. Companies like Amazon (NASDAQ: AMZN) and SKC (KRX: 011790)—through its subsidiary Absolics—are already exploring how glass can facilitate this transition to optical computing.

    The primary challenge remains the "fragility gap." As chips become larger and more complex, the risk of a microscopic crack ruining a multi-thousand-dollar processor is a major hurdle. Experts predict that the next two years will see a surge in innovation regarding "tempered" glass substrates and specialized protective coatings to mitigate these risks.

    A Paradigm Shift in Semiconductor History

    The transition to glass substrates represents one of the most significant material changes in semiconductor history. It marks the end of the organic era for high-performance computing and the beginning of a new age where the package is as critical as the silicon it holds. By breaking the "warpage wall," Intel, Samsung, and TSMC are ensuring that the hardware requirements of artificial intelligence do not outpace the physical capabilities of our materials.

    Key takeaways from this shift include the 10x increase in interconnect density, the move toward rectangular panel-level packaging, and the critical role of glass in enabling future optical interconnects. While the transition is currently expensive and technically challenging, the performance benefits are too great to ignore. In the coming weeks and months, the industry will be watching for the first yield reports from Absolics’ Georgia facility and further details on NVIDIA’s integration of glass into its 2027 roadmap. The "Glass Age" of semiconductors has officially arrived.

  • Glass Substrates: The Breakthrough Material for Next-Generation AI Chip Packaging

    Glass Substrates: The Breakthrough Material for Next-Generation AI Chip Packaging

    The semiconductor industry is currently witnessing its most significant materials shift in decades as manufacturers move beyond traditional organic substrates toward glass. Intel Corporation (NASDAQ:INTC) and other industry leaders are pioneering the use of glass substrates, a breakthrough that offers superior thermal stability and allows for significantly tighter interconnect density between chiplets. This transition has become a critical necessity for the next generation of high-power AI accelerators and high-performance computing (HPC) designs, where managing extreme heat and maintaining signal integrity have become the primary engineering hurdles of the era.

    As of early 2026, the transition to glass is no longer a theoretical pursuit but a commercial reality. With the physical limits of organic materials like Ajinomoto Build-up Film (ABF) finally being reached, glass has emerged as the only viable medium to support the massive, multi-die packages required for frontier AI models. This shift is expected to redefine the competitive landscape for chipmakers, as those who master glass packaging will hold a decisive advantage in power efficiency and compute density.

    The Technical Evolution: Shattering the "Warpage Wall"

    The move to glass is driven by the technical exhaustion of organic substrates, which have served the industry for over twenty years. Traditional organic materials possess a high Coefficient of Thermal Expansion (CTE) that differs significantly from the silicon chips they support. As AI chips grow larger and run hotter, this CTE mismatch causes the substrate to warp during the manufacturing process, leading to connection failures. Glass, however, features a CTE that can be tuned to nearly match silicon, providing a level of dimensional stability that was previously impossible. This allows for the creation of massive packages—exceeding 100mm x 100mm—without the risk of structural failure or "warpage" that has plagued recent high-end GPU designs.

    A key technical specification of this advancement is the implementation of Through-Glass Vias (TGVs). Unlike the mechanical drilling required for organic substrates, TGVs can be etched with extreme precision, allowing for interconnect pitches of less than 100 micrometers. This provides a 10-fold increase in routing density compared to traditional methods. Furthermore, the inherent flatness of glass allows for much tighter tolerances in the lithography process, enabling more complex "chiplet" architectures where multiple specialized dies are placed in extremely close proximity to minimize data latency.

    Initial reactions from the AI research community and industry experts have been overwhelmingly positive. Dr. Ann Kelleher, Executive Vice President at Intel, has previously noted that glass substrates would allow the industry to continue scaling toward one trillion transistors on a single package. Industry analysts at Gartner have described the shift as a "once-in-a-generation" pivot, noting that the dielectric properties of glass reduce signal loss by nearly 40%, which translates directly into lower power consumption for the massive data transfers required by Large Language Models (LLMs).

    Strategic Maneuvers: The Battle for Packaging Supremacy

    The commercialization of glass substrates has sparked a fierce competitive race among the world’s leading foundries and memory makers. Intel (NASDAQ:INTC) has leveraged its early R&D investments to establish a $1 billion pilot line in Chandler, Arizona, positioning itself as a leader in the "foundry-first" approach to glass. By offering glass substrates to its foundry customers, Intel aims to reclaim its manufacturing edge over TSMC (NYSE:TSM), which has traditionally dominated the advanced packaging market through its CoWoS (Chip-on-Wafer-on-Substrate) technology.

    However, the competition is rapidly closing the gap. Samsung Electronics (KRX:005930) recently completed a high-volume pilot line in Sejong, South Korea, and is already supplying glass substrate samples to major U.S. cloud service providers. Meanwhile, SK Hynix (KRX:000660), through its subsidiary Absolics, has taken a significant lead in the merchant market. Its facility in Covington, Georgia, is the first in the world to begin shipping commercial-grade glass substrates as of late 2025, primarily targeting customers like Advanced Micro Devices, Inc. (NASDAQ:AMD) and Amazon.com, Inc. (NASDAQ:AMZN) for their custom AI silicon.

    This development fundamentally shifts the market positioning of major AI labs and tech giants. Companies like NVIDIA (NASDAQ:NVDA), which are constantly pushing the limits of chip size, stand to benefit the most. By adopting glass substrates for its upcoming "Rubin" architecture, NVIDIA can integrate more High Bandwidth Memory (HBM4) stacks around its GPUs, effectively doubling the memory bandwidth available to AI researchers. For startups and smaller AI firms, the availability of standardized glass substrates through merchant suppliers like Absolics could lower the barrier to entry for designing high-performance custom ASICs.

    Broader Significance: Moore’s Law and the Energy Crisis

    The significance of glass substrates extends far beyond the technical specifications of a single chip; it represents a fundamental shift in how the industry approaches the end of Moore’s Law. As traditional transistor scaling slows down, the industry has turned to "system-level scaling," where the package itself becomes as important as the silicon it holds. Glass is the enabling material for this new era, allowing for a level of integration that bridges the gap between individual chips and entire circuit boards.

    Furthermore, the adoption of glass is a critical step in addressing the AI industry's burgeoning energy crisis. Data centers currently consume a significant portion of global electricity, much of which is lost as heat during data movement between processors and memory. The superior signal integrity and reduced dielectric loss of glass allow for 50% less power consumption in the interconnect layers. This efficiency is vital for the long-term sustainability of AI development, where the carbon footprint of training massive models remains a primary public concern.

    Comparisons are already being drawn to previous milestones, such as the introduction of FinFET transistors or the shift to Extreme Ultraviolet (EUV) lithography. Like those breakthroughs, glass substrates solve a physical "dead end" in manufacturing. Without this transition, the industry would have hit a "warpage wall," effectively capping the size and power of AI accelerators and stalling the progress of generative AI and scientific computing.

    The Horizon: From AI Accelerators to Silicon Photonics

    Looking ahead, the roadmap for glass substrates suggests even more radical changes in the near term. Experts predict that by 2027, the industry will move toward "integrated optics," where the transparency and thermal properties of glass enable silicon photonics—the use of light instead of electricity to move data—directly on the substrate. This would virtually eliminate the latency and heat associated with copper wiring, paving the way for AI clusters that operate at speeds currently considered impossible.

    In the long term, while glass is currently reserved for high-end AI and HPC applications due to its cost, it is expected to trickle down into consumer hardware. By 2028 or 2029, we may see "glass-core" processors in enthusiast-grade gaming PCs and workstations, where thermal management is a constant struggle. However, several challenges remain, including the fragility of glass during the handling process and the need for a completely new supply chain for high-volume manufacturing tools, which companies like Applied Materials (NASDAQ:AMAT) are currently rushing to fill.

    What experts predict next is a "rectangular revolution." Because glass can be manufactured in large, rectangular panels rather than the circular wafers used for silicon, the yield and efficiency of chip packaging are expected to skyrocket. This shift toward panel-level packaging will likely be the next major announcement from TSMC and Samsung as they seek to optimize the cost of glass-based systems.

    A New Foundation for the Intelligence Age

    The transition to glass substrates marks a definitive turning point in semiconductor history. It is the moment when the industry moved beyond the limitations of organic chemistry and embraced the stability and precision of glass to build the world's most complex machines. The key takeaways are clear: glass enables larger, more powerful, and more efficient AI chips that will define the next decade of computing.

    As we move through 2026, the industry will be watching for the first commercial deployments of glass-based systems in flagship AI products. The success of Intel’s 18A node and NVIDIA’s Rubin GPUs will serve as the ultimate litmus test for this technology. While the transition involves significant capital investment and engineering risk, the rewards—a sustainable path for AI growth and a new frontier for chip architecture—are far too great to ignore. Glass is no longer just for windows and screens; it is the new foundation of artificial intelligence.

  • The Glass Frontier: Intel and the High-Stakes Race to Redefine AI Supercomputing

    The Glass Frontier: Intel and the High-Stakes Race to Redefine AI Supercomputing

    As the calendar turns to 2026, the semiconductor industry is standing on the precipice of its most significant architectural shift in decades. The traditional organic substrates that have supported the world’s microchips for over twenty years have finally hit a physical wall, unable to handle the extreme heat and massive interconnect demands of the generative AI era. Leading this charge is Intel (NASDAQ: INTC), which has successfully moved its glass substrate technology from the research lab to the manufacturing floor, marking a pivotal moment in the quest to pack one trillion transistors onto a single package by 2030.

    The transition to glass is not merely a material swap; it is a fundamental reimagining of how chips are built and cooled. With the massive compute requirements of next-generation Large Language Models (LLMs) pushing hardware to its limits, the industry’s pivot toward glass represents a "break-the-glass" moment for Moore’s Law. By replacing organic resins with high-purity glass, manufacturers are unlocking levels of precision and thermal resilience that were previously thought impossible, effectively clearing the path for the next decade of AI scaling.

    The Technical Leap: Why Glass is the Future of Silicon

    At the heart of this revolution is the move away from organic materials like Ajinomoto Build-up Film (ABF), which suffer from significant warpage and shrinkage when exposed to the high temperatures required for advanced packaging. Intel’s glass substrates offer a 50% improvement in pattern distortion and superior flatness, allowing for much tighter "depth of focus" during lithography. This precision is critical for the 2026-era 18A and 14A process nodes, where even a microscopic misalignment can render a chip useless.

    Technically, the most staggering specification is the 10x increase in interconnect density. Intel utilizes Through-Glass Vias (TGVs)—microscopic vertical pathways—with pitches far tighter than those achievable in organic materials. This enables a massive surge in the number of chiplets that can communicate within a single package, facilitating the ultra-fast data transfer rates required for AI training. Furthermore, glass possesses a "tunable" Coefficient of Thermal Expansion (CTE) that can be matched almost perfectly to the silicon die itself. This means that as the chip heats up during intense workloads, the substrate and the silicon expand at the same rate, preventing the mechanical stress and "warpage" that plagues current high-end AI accelerators.

    Initial reactions from the AI research community have been overwhelmingly positive, with experts noting that glass substrates solve the "packaging bottleneck" that threatened to stall the progress of GPU and NPU development. Unlike organic substrates, which begin to deform at temperatures above 250°C, glass remains stable at much higher ranges, allowing engineers to push power envelopes further than ever before. This thermal headroom is essential for the 1,000-watt-plus TDPs (Thermal Design Power) now becoming common in enterprise AI hardware.

    A New Competitive Battlefield: Intel, Samsung, and the Packaging Wars

    The move to glass has ignited a fierce competition among the world’s leading foundries. While Intel (NASDAQ: INTC) pioneered the research, it is no longer alone. Samsung (KRX: 005930) has aggressively fast-tracked its "dream substrate" program, completing a pilot line in Sejong, South Korea, and poaching veteran packaging talent to bridge the gap. Samsung is currently positioning its glass solutions for the 2027 mobile and server markets, aiming to integrate them into its next-generation Exynos and AI chipsets.

    Meanwhile, Taiwan Semiconductor Manufacturing Co. (NYSE: TSM) has shifted its focus toward Chip-on-Panel-on-Substrate (CoPoS) technology. By leveraging glass in a panel-level format, TSMC aims to alleviate the supply chain constraints that have historically hampered its CoWoS (Chip-on-Wafer-on-Substrate) production. As of early 2026, TSMC is already sampling glass-based solutions for major clients like NVIDIA (NASDAQ: NVDA), ensuring that the dominant player in AI chips remains at the cutting edge of packaging technology.

    The competitive landscape is further complicated by the arrival of Absolics, a subsidiary of SKC (KRX: 011790). Having completed a massive $600 million production facility in Georgia, USA, Absolics has become the first merchant supplier to ship commercial-grade glass substrates to US-based tech giants, reportedly including Amazon (NASDAQ: AMZN) and AMD (NASDAQ: AMD). This creates a strategic advantage for companies that do not own their own foundries but require the performance benefits of glass to compete with Intel’s vertically integrated offerings.

    Extending Moore’s Law in the AI Era

    The broader significance of the glass substrate shift cannot be overstated. For years, skeptics have predicted the end of Moore’s Law as the physical limits of transistor shrinking were reached. Glass substrates provide a "system-level" extension of this law. By allowing for larger package sizes—exceeding 120mm by 120mm—glass enables the creation of "System-on-Package" designs that can house dozens of chiplets, effectively creating a supercomputer on a single substrate.

    This development is a direct response to the "AI Power Crisis." Because glass allows for the direct embedding of passive components like inductors and capacitors, and facilitates the integration of optical interconnects, it significantly reduces power delivery losses. In a world where AI data centers are consuming an ever-growing share of the global power grid, the efficiency gains provided by glass are a critical environmental and economic necessity.

    Compared to previous milestones, such as the introduction of FinFET transistors or Extreme Ultraviolet (EUV) lithography, the shift to glass is unique because it focuses on the "envelope" of the chip rather than just the circuitry inside. It represents a transition from "More Moore" (scaling transistors) to "More than Moore" (scaling the package). This holistic approach is what will allow the industry to reach the 1-trillion transistor milestone, a feat that would be physically impossible using 2024-era organic packaging technologies.

    The Horizon: Integrated Optics and the Path to 2030

    Looking ahead, the next two to three years will see the first high-volume consumer applications of glass substrates. While the initial rollout in 2026 is focused on high-end AI servers and supercomputers, the technology is expected to trickle down to high-end workstations and gaming PCs by 2028. One of the most anticipated near-term developments is the "Optical I/O" revolution. Because glass is transparent and thermally stable, it is the perfect medium for integrated silicon photonics, allowing data to be moved via light rather than electricity directly from the chip package.

    However, challenges remain. The industry must still perfect the high-volume manufacturing of Through-Glass Vias without compromising structural integrity, and the supply chain for high-purity glass panels must be scaled to meet global demand. Experts predict that the next major breakthrough will be the transition to even larger panel sizes, moving from 300mm formats to 600mm panels, which would drastically reduce the cost of glass packaging and make it viable for mid-range consumer electronics.

    Conclusion: A Clear Vision for the Future of Computing

    The move toward glass substrates marks the beginning of a new epoch in semiconductor manufacturing. Intel’s early leadership has forced a rapid evolution across the entire ecosystem, bringing competitors like Samsung and TSMC into a high-stakes race that benefits the entire AI industry. By solving the thermal and density limitations of organic materials, glass has effectively removed the ceiling that was hovering over AI hardware development.

    As we move further into 2026, the success of these first commercial glass-packaged chips will be the metric by which the next generation of computing is judged. The significance of this development in AI history is profound; it is the physical foundation upon which the next decade of artificial intelligence will be built. For investors and tech enthusiasts alike, the coming months will be a critical period to watch as Intel and its rivals move from pilot lines to the massive scale required to power the world’s AI ambitions.
