    The Silicon Lego Revolution: How 3.5D Packaging and UCIe are Building the Next Generation of AI Superchips

    As of early 2026, the semiconductor landscape has reached a historic turning point, moving definitively away from the monolithic chip designs that defined the last fifty years. In their place, a new architecture known as 3.5D Advanced Packaging has emerged, powered by the Universal Chiplet Interconnect Express (UCIe) 3.0 standard. This development is not merely an incremental upgrade; it represents a fundamental shift in how artificial intelligence hardware is conceived, manufactured, and scaled, effectively turning the world’s most advanced silicon into a "plug-and-play" ecosystem.

    The immediate significance of this transition is staggering. By moving away from "all-in-one" chips toward a modular "Silicon Lego" approach, the industry is overcoming the physical limits of traditional lithography. AI giants are no longer constrained by the maximum size of a single wafer exposure (the reticle limit). Instead, they are assembling massive "superchips" that combine specialized compute tiles, memory, and I/O from various sources into a single, high-performance package. This breakthrough is the engine behind the quadrillion-parameter AI models currently entering training cycles, providing the raw bandwidth and thermal efficiency necessary to sustain the next era of generative intelligence.

    The 1,000x Leap: Hybrid Bonding and 3.5D Architectures

    At the heart of this revolution is the commercialization of Copper-to-Copper (Cu-Cu) Hybrid Bonding. Traditional 2.5D packaging, which places chips side-by-side on a silicon interposer, relies on microbumps for connectivity. These bumps typically have a pitch of 40 to 50 micrometers. However, early 2026 has seen the mainstream adoption of Hybrid Bonding with pitches as low as 1 to 6 micrometers. Because interconnect density scales with the square of the pitch reduction, moving from a 50-micrometer bump to a 5-micrometer hybrid bond results in a 100x increase in area density. At the sub-micrometer level being pioneered for ultra-high-end accelerators, the industry is realizing a 1,000x increase in interconnect density compared to 2023 standards.

    This 3.5D architecture combines the lateral scalability of 2.5D with the vertical density of 3D stacking. For instance, Broadcom (NASDAQ: AVGO) recently introduced its XDSiP (Extreme Dimension System in Package) architecture, which enables over 6,000 mm² of silicon in a single package. By stacking accelerator logic dies vertically before placing them on a horizontal interposer surrounded by 16 stacks of HBM4 memory, Broadcom has managed to reduce latency by up to 60% while cutting die-to-die power consumption by a factor of ten. This gapless connection eliminates the parasitic resistance of traditional solder, allowing for bandwidth densities exceeding 10 Tbps/mm.

    The UCIe 3.0 specification, released in late 2025, serves as the "glue" for this hardware. Supporting data rates up to 64 GT/s—double that of the previous generation—UCIe 3.0 introduces a standardized Management Transport Protocol (MTP). This allows for "plug-and-play" interoperability, where an NPU tile from one vendor can be verified and initialized alongside an I/O tile from another. This standardization has been met with overwhelming support from the AI research community, as it allows for the rapid prototyping of specialized hardware configurations tailored to specific neural network architectures.

    The Business of "Systems Foundries" and Chiplet Marketplaces

    The move toward 3.5D packaging is radically altering the competitive strategies of the world’s largest tech companies. TSMC (NYSE: TSM) remains the dominant force, with its CoWoS-L and SoIC-X technologies being the primary choice for NVIDIA’s (NASDAQ: NVDA) new "Vera Rubin" architecture. However, Intel (NASDAQ: INTC) has successfully positioned itself as a "Systems Foundry" with its 18A-PT (Performance-Tuned) node and Foveros Direct 3D technology. By offering advanced packaging services to external customers like Apple (NASDAQ: AAPL) and Qualcomm (NASDAQ: QCOM), Intel is challenging the traditional foundry model, proving that packaging is now as strategically important as transistor fabrication.

    This shift also benefits specialized component makers and EDA (Electronic Design Automation) firms. Companies like Synopsys (NASDAQ: SNPS) and Siemens (ETR: SIE) have released "Digital Twin" modeling tools that allow designers to simulate UCIe 3.0 links before physical fabrication. This is critical for mitigating the risk of "known good die" (KGD) failures, where one faulty chiplet could ruin an entire expensive 3.5D assembly. For startups, this ecosystem is a godsend; a small AI chip firm can now focus on designing a single, world-class NPU chiplet and rely on a standardized ecosystem to integrate it with industry-standard I/O and memory, rather than having to design a massive, risky monolithic chip from scratch.

    Strategic advantages are also shifting toward those who control the memory supply chain. Samsung (KRX: 005930) is leveraging its unique position as both a memory manufacturer and a foundry to integrate HBM4 directly with custom logic dies using its X-Cube 3D technology. By moving logic dies to a 2nm process for tighter integration with memory stacks, Samsung is aiming to eliminate the "memory wall" that has long throttled AI performance. This vertical integration allows for a more cohesive design process, potentially offering higher yields and lower costs for high-volume AI accelerators.

    Beyond Moore’s Law: A New Era of AI Scalability

    The wider significance of 3.5D packaging and UCIe cannot be overstated; it represents the "End of the Monolithic Era." For decades, the industry followed Moore’s Law by shrinking transistors. While that continues, the primary driver of performance has shifted to interconnect architecture. By disaggregating a massive 800mm² GPU into eight smaller 100mm² chiplets, manufacturers can significantly increase wafer yields. A single defect that would have ruined a massive "superchip" now only ruins one small tile, drastically reducing waste and cost.

    Furthermore, this modularity allows for "node mixing." High-performance logic can be restricted to the most expensive 2nm or 1.4nm nodes, while less sensitive components like I/O and memory controllers can be "back-ported" to cheaper, more mature 6nm or 5nm nodes. This optimizes the total cost per transistor and ensures that leading-edge fab capacity is reserved for the most critical components. This pragmatic approach to scaling mirrors the evolution of software from monolithic applications to microservices, suggesting a permanent change in how we think about compute hardware.

    However, the rise of the chiplet ecosystem does bring concerns, particularly regarding thermal management. Stacking high-power logic dies vertically creates intense heat pockets that traditional air cooling cannot handle. This has sparked a secondary boom in liquid-cooling technologies and "rack-scale" integration, where the chip, the package, and the cooling system are designed as a single unit. As AMD (NASDAQ: AMD) prepares its Instinct MI400 for release later in 2026, the focus is as much on the liquid-cooled "CDNA 5" architecture as it is on the raw teraflops of the silicon.

    The Future: HBM5, 1.4nm, and the Chiplet Marketplace

    Looking ahead, the industry is already eyeing the transition to HBM5 and the integration of 1.4nm process nodes into 3.5D stacks. We expect to see the emergence of a true "chiplet marketplace" by 2027, where hardware designers can browse a catalog of verified UCIe-compliant dies for various functions—cryptography, video encoding, or specific AI kernels—and have them assembled into a custom ASIC in a fraction of the time it takes today. This will likely lead to a surge in "domain-specific" AI hardware, where chips are optimized for specific tasks like real-time translation or autonomous vehicle edge-processing.

    The long-term challenges remain significant. Standardizing test and assembly processes across different foundries will require unprecedented cooperation between rivals. Furthermore, the complexity of 3.5D power delivery—getting electricity into the middle of a stack of chips—remains a major engineering hurdle. Experts predict that the next few years will see the rise of "backside power delivery" (BSPD) as a standard feature in 3.5D designs to address these power and thermal constraints.

    A Fundamental Paradigm Shift

    The convergence of 3.5D packaging, Hybrid Bonding, and the UCIe 3.0 standard marks the beginning of a new epoch in computing. We have moved from the era of "scaling down" to the era of "scaling out" within the package. This development is as significant to AI history as the transition from CPUs to GPUs was a decade ago. It provides the physical infrastructure necessary to support the transition from generative AI to "Agentic AI" and beyond, where models require near-instantaneous access to massive datasets.

    In the coming weeks and months, the industry will be watching the first production yields of NVIDIA’s Rubin and AMD’s MI400. These products will serve as the litmus test for the viability of 3.5D packaging at massive scale. If successful, the "Silicon Lego" model will become the default blueprint for all high-performance computing, ensuring that the limits of AI are defined not by the size of a single piece of silicon, but by the creativity of the architects who assemble them.

    The insatiable demand for ever-increasing computational power and efficiency in Artificial Intelligence (AI) applications is pushing the boundaries of traditional silicon-based semiconductor manufacturing. As the industry grapples with the physical limits of transistor scaling, a new era of innovation is dawning, driven by groundbreaking advancements in semiconductor materials and sophisticated advanced packaging techniques. These emerging technologies, including 3D packaging, chiplets, and hybrid bonding, are not merely incremental improvements; they represent a fundamental shift in how AI chips are designed and fabricated, promising unprecedented levels of performance, power efficiency, and functionality.

    These innovations are critical for powering the next generation of AI, from colossal large language models (LLMs) in hyperscale data centers to compact, energy-efficient AI at the edge. By enabling denser integration, faster data transfer, and superior thermal management, these advancements are poised to accelerate AI development, unlock new capabilities, and reshape the competitive landscape of the global technology industry. The convergence of novel materials and advanced packaging is set to be the cornerstone of future AI breakthroughs, addressing bottlenecks that traditional methods can no longer overcome.

    The Architectural Revolution: 3D Stacking, Chiplets, and Hybrid Bonding Unleashed

    The core of this revolution lies in moving beyond the flat, monolithic chip design to a three-dimensional, modular architecture. This paradigm shift involves several key technical advancements that work in concert to enhance AI chip performance and efficiency dramatically.

    3D Packaging, encompassing 2.5D and true vertical stacking, is at the forefront. Instead of placing components side-by-side on a large, expensive silicon die, chips are stacked vertically, drastically shortening the physical distance data must travel between compute units and memory. This directly translates to vastly increased memory bandwidth and significantly reduced latency – two critical factors for AI workloads, which are often memory-bound and require rapid access to massive datasets. Companies like TSMC (NYSE: TSM) are leaders in this space with their CoWoS (Chip-on-Wafer-on-Substrate) technology, a 2.5D packaging solution widely adopted for high-performance AI accelerators such as NVIDIA's (NASDAQ: NVDA) H100. Intel (NASDAQ: INTC) is also heavily invested with Foveros (3D stacking) and EMIB (Embedded Multi-die Interconnect Bridge), while Samsung (KRX: 005930) offers I-Cube (2.5D) and X-Cube (3D stacking) platforms.

    Complementing 3D packaging are Chiplets, a modular design approach where a complex System-on-Chip (SoC) is disaggregated into smaller, specialized "chiplets" (e.g., CPU, GPU, memory, I/O, AI accelerators). These chiplets are then integrated into a single package using advanced packaging techniques. This offers unparalleled flexibility, allowing designers to mix and match different chiplets, each manufactured on the most optimal (and cost-effective) process node for its specific function. This heterogeneous integration is particularly beneficial for AI, enabling the creation of highly customized accelerators tailored for specific workloads. AMD (NASDAQ: AMD) has been a pioneer in this area, utilizing chiplets with 3D V-cache in its Ryzen processors and integrating CPU/GPU tiles in its Instinct MI300 series.

    The glue that binds these advanced architectures together is Hybrid Bonding. This cutting-edge direct copper-to-copper (Cu-Cu) bonding technology creates ultra-dense vertical interconnections between dies or wafers at pitches below 10 µm, even approaching sub-micron levels. Unlike traditional methods that rely on solder or intermediate materials, hybrid bonding forms direct metal-to-metal connections, dramatically increasing I/O density and bandwidth while minimizing parasitic capacitance and resistance. This leads to lower latency, reduced power consumption, and improved thermal conduction, all vital for the demanding power and thermal requirements of AI chips. IBM Research and ASMPT have achieved significant milestones, pushing interconnection sizes to around 0.8 microns, enabling over 1000 GB/s bandwidth with high energy efficiency.

    These advancements represent a significant departure from the monolithic chip design philosophy. Previous approaches focused primarily on shrinking transistors on a single die (Moore's Law). While transistor scaling remains important, advanced packaging and chiplets offer a new dimension of performance scaling by optimizing inter-chip communication and allowing for heterogeneous integration. The initial reactions from the AI research community and industry experts are overwhelmingly positive, recognizing these techniques as essential for sustaining the pace of AI innovation. They are seen as crucial for breaking the "memory wall" and enabling the power-efficient processing required for increasingly complex AI models.

    Reshaping the AI Competitive Landscape

    NVIDIA (NASDAQ: NVDA), a dominant player in AI hardware, stands to benefit immensely. Their cutting-edge GPUs, like the H100, already leverage TSMC's CoWoS 2.5D packaging to integrate the GPU die with high-bandwidth memory (HBM). As 3D stacking and hybrid bonding become more prevalent, NVIDIA can further optimize its accelerators for even greater performance and efficiency, maintaining its lead in the AI training and inference markets. The ability to integrate more specialized AI acceleration chiplets will be key.

    Intel (NASDAQ: INTC), is strategically positioning itself to regain market share in the AI space through its robust investments in advanced packaging technologies like Foveros and EMIB. By leveraging these capabilities, Intel aims to offer highly competitive AI accelerators and CPUs that integrate diverse computing elements, challenging NVIDIA and AMD. Their foundry services, offering these advanced packaging options to third parties, could also become a significant revenue stream and influence the broader ecosystem.

    AMD (NASDAQ: AMD) has already demonstrated its prowess with chiplet-based designs in its CPUs and GPUs, particularly with its Instinct MI300 series, which combines CPU and GPU elements with HBM using advanced packaging. Their early adoption and expertise in chiplets give them a strong competitive edge, allowing for flexible, cost-effective, and high-performance solutions tailored for various AI workloads.

    Foundries like TSMC (NYSE: TSM) and Samsung (KRX: 005930) are critical enablers.

Their ability to provide cutting-edge packaging services will determine who can bring the most performant and efficient AI chips to market. The competition between these foundries to offer the most advanced 2.5D/3D integration and hybrid bonding capabilities will be fierce.

    Beyond the major chip designers, companies specializing in advanced materials like Wolfspeed (NYSE: WOLF), Infineon (FSE: IFX), and Navitas Semiconductor (NASDAQ: NVTS) are becoming increasingly vital. Their wide-bandgap materials (SiC and GaN) are crucial for power management in AI data centers, where power efficiency is paramount. Startups focusing on novel 2D materials or specialized chiplet designs could also find niches, offering custom solutions for emerging AI applications.

    The potential disruption to existing products and services is significant. Monolithic chip designs will increasingly struggle to compete with the performance and efficiency offered by advanced packaging and chiplets, particularly for demanding AI tasks. Companies that fail to adopt these architectural shifts risk falling behind. Market positioning will increasingly depend not just on transistor technology but also on expertise in heterogeneous integration, thermal management, and robust supply chains for advanced packaging.

    Wider Significance and Broad AI Impact

    These advancements in semiconductor materials and advanced packaging are more than just technical marvels; they represent a pivotal moment in the broader AI landscape, addressing fundamental limitations and paving the way for unprecedented capabilities.

    Foremost, these innovations are directly addressing the slowdown of Moore's Law. While transistor density continues to increase, the rate of performance improvement per dollar has decelerated. Advanced packaging offers a "More than Moore" solution, providing performance gains by optimizing inter-component communication and integration rather than solely relying on transistor shrinks. This allows for continued progress in AI chip capabilities even as the physical limits of silicon are approached.

    The trajectory for these emerging trends points towards even more sophisticated integration and specialized materials, with significant implications for future AI applications.

    In the near term, we can expect to see wider adoption of 2.5D and 3D packaging across a broader range of AI accelerators, moving beyond just the highest-end data center chips. Hybrid bonding will become increasingly common for integrating memory and compute, pushing interconnect densities even further. The UCIe (Universal Chiplet Interconnect Express) standard will gain traction, fostering a more open and interoperable chiplet ecosystem, allowing companies to mix and match chiplets from different vendors. This will drive down costs and accelerate innovation by democratizing access to specialized IP.

    Long-term developments include the deeper integration of novel materials. While 2D materials like graphene and molybdenum disulfide are still primarily in research, breakthroughs in fabricating semiconducting graphene with useful bandgaps suggest future possibilities for ultra-thin, high-mobility transistors that could be heterogeneously integrated with silicon. Silicon Carbide (SiC) and Gallium Nitride (GaN) will continue to mature, not just for power electronics but potentially for high-frequency AI processing at the edge, enabling extremely compact and efficient AI devices for IoT and mobile applications. We might also see the integration of optical interconnects within 3D packages to further reduce latency and increase bandwidth for inter-chiplet communication.

    Challenges remain formidable. Thermal management in densely packed 3D stacks is a critical hurdle, requiring innovative cooling solutions and thermal interface materials. Ensuring manufacturing yield and reliability for complex multi-chiplet, 3D stacked systems is another significant engineering task. Furthermore, the development of robust design tools and methodologies that can efficiently handle the complexities of heterogeneous integration and 3D layout is essential.

    Experts predict that the future of AI hardware will be defined by highly specialized, heterogeneously integrated systems, meticulously optimized for specific AI workloads. This will move away from general-purpose computing towards purpose-built AI engines. The emphasis will be on system-level performance, power efficiency, and cost-effectiveness, with packaging becoming as important as the transistors themselves. What experts predict is a future where AI accelerators are not just faster, but also smarter in how they manage and move data, driven by these architectural and material innovations.

    A New Era for AI Hardware

    The convergence of emerging semiconductor materials and advanced packaging techniques marks a transformative period for AI hardware. The shift from monolithic silicon to modular, three-dimensional architectures utilizing chiplets, 3D stacking, and hybrid bonding, alongside the exploration of wide-bandgap and 2D materials, is fundamentally reshaping the capabilities of AI chips. These innovations are critical for overcoming the limitations of traditional transistor scaling, providing the unprecedented bandwidth, lower latency, and improved power efficiency demanded by today's and tomorrow's sophisticated AI models.

    The significance of this development in AI history cannot be overstated. It is a foundational change that enables the continued exponential growth of AI capabilities, much like the invention of the transistor itself or the advent of parallel computing with GPUs. It signifies a move towards a more holistic, system-level approach to chip design, where packaging is no longer a mere enclosure but an active component in enhancing performance.

These groundbreaking innovations are no longer mere afterthoughts in the chip-making process; they are now the critical enablers for unlocking the true potential of AI, fundamentally reshaping how AI chips are built and perform.

    These sophisticated packaging techniques are immediately significant because they directly address the most formidable bottlenecks in AI hardware, particularly the infamous "memory wall." By allowing for unprecedented levels of integration between processing units and high-bandwidth memory, advanced packaging dramatically boosts data transfer rates, slashes latency, and enables a much higher computational density. This paradigm shift is not just an incremental improvement; it is a foundational leap that will empower the development of more complex, power-efficient, and smaller AI devices, from edge computing to hyperscale data centers, thereby fueling the next wave of AI breakthroughs.

    The Technical Core: Engineering AI's Performance Edge

    The advancements in semiconductor packaging represent a diverse toolkit, each method offering unique advantages for enhancing AI chip capabilities. These innovations move beyond traditional 2D integration, which places components side-by-side on a single substrate, by enabling vertical stacking and heterogeneous integration.

    2.5D Packaging (e.g., CoWoS, EMIB): This approach, pioneered by companies like TSMC (NYSE: TSM) with its CoWoS (Chip-on-Wafer-on-Substrate) and Intel (NASDAQ: INTC) with EMIB (Embedded Multi-die Interconnect Bridge), involves placing multiple bare dies, such as a GPU and High-Bandwidth Memory (HBM) stacks, on a shared silicon or organic interposer. The interposer acts as a high-speed communication bridge, drastically shortening signal paths between logic and memory. This provides an ultra-wide communication bus, crucial for data-intensive AI workloads, effectively mitigating the "memory wall" problem and enabling higher throughput for AI model training and inference. Compared to traditional package-on-package (PoP) or system-in-package (SiP) solutions with longer traces, 2.5D offers superior bandwidth and lower latency.

    3D Stacking and Through-Silicon Vias (TSVs): Representing a true vertical integration, 3D stacking involves placing multiple active dies or wafers directly atop one another. The enabling technology here is Through-Silicon Vias (TSVs) – vertical electrical connections that pass directly through the silicon dies, facilitating direct communication and power transfer between layers. This offers unparalleled bandwidth and even lower latency than 2.5D solutions, as signals travel minimal distances. The primary difference from 2.5D is the direct vertical connection, allowing for significantly higher integration density and more powerful AI hardware within a smaller footprint. While thermal management is a challenge due to increased density, innovations in microfluidic cooling are being developed to address this.

    Hybrid Bonding: This cutting-edge 3D packaging technique facilitates direct copper-to-copper (Cu-Cu) connections at the wafer or die-to-wafer level, bypassing traditional solder bumps. Hybrid bonding achieves ultra-fine interconnect pitches, often in the single-digit micrometer range, a significant improvement over conventional microbump technology. This results in ultra-dense interconnects and bandwidths up to 1000 GB/s, bolstering signal integrity and efficiency. For AI, this means even shorter signal paths, lower parasitic resistance and capacitance, and ultimately, more efficient and compact HBM stacks crucial for memory-bound AI accelerators.

    Chiplet Technology: Instead of a single, large monolithic chip, chiplet technology breaks down a system into several smaller, functional integrated circuits (ICs), or "chiplets," each optimized for a specific task. These chiplets (e.g., CPU, GPU, memory, AI accelerators) are then interconnected within a single package. This modular approach supports heterogeneous integration, allowing different functions to be fabricated on their most optimal process node (e.g., compute cores on 3nm, I/O dies on 7nm). This not only improves overall energy efficiency by 30-40% for the same workload but also allows for performance scalability, specialization, and overcomes the physical limitations (reticle limits) of monolithic die size. Initial reactions from the AI research community highlight chiplets as a game-changer for custom AI hardware, enabling faster iteration and specialized designs.

    Fan-Out Packaging (FOWLP/FOPLP): Fan-out packaging eliminates the need for traditional package substrates by embedding dies directly into a molding compound, allowing for more I/O connections in a smaller footprint. Fan-out Panel-Level Packaging (FOPLP) is an advanced variant that reassembles chips on a larger panel instead of a wafer, enabling higher throughput and lower cost. These methods provide higher I/O density, improved signal integrity due to shorter electrical paths, and better thermal performance, all while significantly reducing the package size.

By enabling the seamless integration of diverse, specialized components into a single, optimized package, advanced packaging is not just an incremental improvement; it is a foundational transformation that directly addresses the "memory wall" bottleneck and fuels the rapid advancement of AI capabilities across various sectors.

    The Technical Marvels Underpinning AI's Leap Forward

    The core of this revolution lies in several sophisticated packaging techniques that enable a new level of integration and performance. These technologies depart significantly from conventional 2D packaging, which typically places individual chips on a planar Printed Circuit Board (PCB), leading to longer signal paths and higher latency.

    2.5D Packaging, exemplified by Taiwan Semiconductor Manufacturing Company (TSMC) (NYSE: TSM)'s CoWoS (Chip-on-Wafer-on-Substrate) and Intel (NASDAQ: INTC)'s Embedded Multi-die Interconnect Bridge (EMIB), involves placing multiple active dies—such as a powerful GPU and High-Bandwidth Memory (HBM) stacks—side-by-side on a high-density silicon or organic interposer. This interposer acts as a miniature, high-speed wiring board, drastically shortening interconnect distances from centimeters to millimeters. This reduction in path length significantly boosts signal integrity, lowers latency, and reduces power consumption for inter-chip communication. NVIDIA (NASDAQ: NVDA)'s H100 and A100 series GPUs, along with Advanced Micro Devices (AMD) (NASDAQ: AMD)'s Instinct MI300A accelerators, are prominent examples leveraging 2.5D integration for unparalleled AI performance.

    3D Packaging, or 3D-IC, takes vertical integration to the next level by stacking multiple active semiconductor dies directly on top of each other. These layers are interconnected through Through-Silicon Vias (TSVs), tiny electrical conduits etched directly through the silicon. This vertical stacking minimizes footprint, maximizes integration density, and offers the shortest possible interconnects, leading to superior speed and power efficiency. Samsung (KRX: 005930)'s X-Cube and Intel's Foveros are leading 3D packaging technologies, with AMD utilizing TSMC's 3D SoIC (System-on-Integrated-Chips) for its Ryzen 7000X3D CPUs and EPYC processors.

    A cutting-edge advancement, Hybrid Bonding, forms direct, molecular-level connections between metal pads of two or more dies or wafers, eliminating the need for traditional solder bumps. This technology is critical for achieving interconnect pitches below 10 µm, with copper-to-copper (Cu-Cu) hybrid bonding reaching single-digit micrometer ranges. Hybrid bonding offers vastly higher interconnect density, shorter wiring distances, and superior electrical performance, leading to thinner, faster, and more efficient chips. NVIDIA's Hopper and Blackwell series AI GPUs, along with upcoming Apple (NASDAQ: AAPL) M5 series AI chips, are expected to heavily rely on hybrid bonding.

    Finally, Fan-Out Wafer-Level Packaging (FOWLP) is a cost-effective, high-performance solution. Here, individual dies are repositioned on a carrier wafer or panel, with space around each die for "fan-out." A Redistribution Layer (RDL) is then formed over the entire molded area, creating fine metal traces that "fan out" from the chip's original I/O pads to a larger array of external contacts. This approach allows for a higher I/O count, better signal integrity, and a thinner package compared to traditional fan-in packaging. TSMC's InFO (Integrated Fan-Out) technology, famously used in Apple's A-series processors, is a prime example, and NVIDIA is reportedly considering Fan-Out Panel Level Packaging (FOPLP) for its GB200 AI server chips due to CoWoS capacity constraints.

    The initial reaction from the AI research community and industry experts has been overwhelmingly positive.
