AI is reshaping industries, economies, and daily life at an unprecedented speed. From generative AI and autonomous systems to high-performance computing (HPC) applications in science, defense, and advanced manufacturing, the demand for computational power is accelerating exponentially. But while algorithms capture the spotlight, the true enabler of this transformation lies deeper, in the physical infrastructure that makes AI possible.
Performance in the AI era is no longer defined by transistor shrink alone. It is increasingly defined by how efficient systems are integrated, interconnected, cooled, and manufactured at scale. As Moore’s Law slows, innovation has shifted from simple transistor scaling to advanced packaging, heterogeneous integration, and precision interconnect engineering. In this new paradigm, packaging is performance.
At the center of this transformation is the interconnect stack, from high layer count PCBs and HDI routing to package substrates, silicon interposers, hybrid bonding, and high bandwidth memory (HBM). Every layer must operate in perfect harmony. Signal integrity, thermal stability, yield, dimensional control, contamination mitigation, and atomic-level surface precision all determine whether AI systems scale efficiently or stall under complexity.
MKS stands uniquely positioned at this intersection of materials science, photonics, and vacuum engineering, enabling the foundational technologies that power next-generation AI and HPC infrastructure.
The Shift: From Transistor Scaling to System Integration
For decades, performance gains were driven primarily by transistor miniaturization. Today, the scaling frontier has moved outward. Advanced packaging now integrates multiple specialized dies—logic processors, graphics processing units (GPUs), AI accelerators, and stacked HBM—into tightly coupled system-in-package architectures.
These architectures demand:
- Ultra-fine redistribution layers
- High aspect ratio microvias and through-silicon vias (TSVs)
- Sub-5-micron line and space geometries
- Hybrid bonding for wafer-to-wafer and die-to-wafer connections at near-atomic precision
- Controlled copper deposition with minimal stress
- Extreme thermal and power density management
