As AI pushes chip packages beyond traditional wafer limits, panel-level processing is emerging as a critical path to scale advanced packaging for the next decade of compute. Lam Research is helping make that shift possible through decades of advanced packaging experience and new investments in panel-level R&D and manufacturing readiness.
Increasingly, AI systems performance is no longer defined by a single chip, but rather the combined capabilities and efficiency of processors, memory, and interconnects work together as a system – or package. That shift has elevated advanced packaging from a manufacturing afterthought to one of the industry’s most important innovation frontiers.
Now the industry is approaching another transition. As AI packages become larger, denser, and more complex, traditional wafer-based manufacturing is starting to encounter practical limits. Increasingly, industry attention is turning to larger-format, panel-level packaging as a pathway to sustain AI scaling for the decade ahead.
Here are five reasons panel-level packaging is gaining traction:
1. Advanced Packaging Has Become the New Engine of AI Scaling
Modern AI accelerators increasingly rely on heterogeneous architectures that combine processors, high-bandwidth memory (HBM), chiplets, and specialized components into tightly integrated systems. Advanced packaging enables these components to function as a unified platform, allowing more data to move faster and more efficiently between compute and memory.
The result is higher bandwidth, lower latency, improved energy efficiency, and more scalable system performance, all essential requirements for training and running large language models and other AI workloads. Without advancements in packaging, many of the gains needed to support the AI era would be difficult to achieve through silicon scaling alone.
2. AI Is Driving Package Sizes Beyond Traditional Limits
The industry’s newest AI architectures are growing larger and more complex.
Advanced packages now integrate multiple chiplets, memory stacks, interposers, and sophisticated interconnect structures. As these designs expand, traditional round wafers become increasingly constrained by factors such as edge losses, area utilization, and manufacturing efficiency.
The typically square or rectangular shape of advanced packages creates a geometry mismatch on a round wafer. As package dimensions grow, fewer large rectangular packages can fit efficiently inside the circular wafer area and more usable space is lost — especially at the wafer edge.
Panel-level packaging is emerging as a scalable manufacturing path for AI systems that require larger packages, more memory, and faster data movement—helping extend advanced packaging for the next decade of compute growth.
This challenge is particularly significant for AI, where designers continually seek to place more compute resources and memory closer together. As package dimensions increase, chipmakers need a new manufacturing approach capable of efficiently supporting larger formats and denser integration schemes.
3. Panel-Level Packaging Offers a More Scalable Manufacturing Model
Rather than using conventional round wafers, panel-level packaging processes square or rectangular panels. The larger format can improve area utilization and create opportunities for greater manufacturing efficiency, particularly as advanced packages continue to increase in size.
The move to panel is not simply a change in substrate shape. It represents a fundamental shift in how advanced packages can be manufactured. Larger processing areas provide a path to accommodate future package dimensions while potentially improving scalability and production economics.
For an industry seeking ways to support sustained AI growth, panel-level processing offers an increasingly attractive route forward.
4. Panel-Level Processing Could Help Remove Future AI Bottlenecks
The semiconductor industry has become adept at identifying bottlenecks before they constrain growth. Today, many experts see advanced packaging as one of the most critical areas requiring investment and innovation.
Panel-level packaging is drawing attention because it addresses a known scaling challenge. As AI systems demand larger dies, denser interconnects, and more sophisticated package architectures, the industry will need manufacturing approaches capable of supporting higher volumes and larger form factors.
Moving to panels is not without challenges. Yield, process control, uniformity, automation, throughput, and industry standardization remain active areas of development. Achieving wafer-level precision across substantially larger substrates will require significant engineering innovation.
Yet those challenges also underscore why many view panel processing as an inflection point rather than an incremental improvement. If successful, it can usher in a new era of package scaling, moving beyond wafer-sized constraints.
5. The Ecosystem Is Already Building Toward the Panel Future
Historically, major transitions in semiconductor manufacturing require collaboration across equipment suppliers, device makers, packaging houses, researchers, and system designers.
The same is true for panel-level packaging. Industry progress will depend on developing new processes, qualifying manufacturing flows, improving yield, and establishing scalable production models. Advanced packaging itself has become an increasingly ecosystem-driven effort, requiring coordination across the semiconductor value chain.
Lam Research has been involved in advanced packaging technologies for more than two decades and is investing in the infrastructure, R&D capabilities, and ecosystem collaboration required to support the industry’s next chapter. Recent investments such as the Salzburg Panel Center of Excellence reflect a broader focus on accelerating panel-level research, qualification, and manufacturing readiness while helping customers prepare for future packaging demands.
Importantly, this effort is not about any single product or platform. It is about helping enable the manufacturing foundations that future AI systems will require.
The Bottom Line
Every major era of semiconductor progress has depended on a manufacturing breakthrough. Transistors made modern computing possible. Lithography extended Moore’s Law. Advanced packaging is now helping unlock the AI era.
The next challenge is scaling advanced packaging itself.
As AI systems demand larger packages, more memory, and faster data movement, the industry needs manufacturing approaches that can support these architectures efficiently and at volume. Panel-level packaging is emerging as one of the strongest paths forward.
The shift from wafer to panel will take time, but its direction is becoming clear. If advanced packaging is the foundation of modern AI compute, panel-level packaging could provide the manufacturing platform for its next decade of growth.
