Industry Analysis
The AI capex surge is triggering a cascading reconfiguration across the semiconductor stack: surging HBM and advanced packaging demand is forcing DRAM makers to accelerate 3D stacking, while EUV lithography and test equipment have become critical bottlenecks. TSMC (Taiwan, China) leverages its 3nm yield leadership to lock in NVIDIA and AMD, yet geopolitical friction inflates its overseas fab costs—Arizona and Japan lines still lag domestic efficiency. FormFactor benefits from rising test complexity but risks customer concentration under U.S. export controls. Texas Instruments’ analog dominance in data center power management delivers high-margin insulation, though custom ASICs pose a long-term threat. Over the next 12–24 months, HBM5 standardization will reshape memory dynamics, while tapering CHIPS Act subsidies may trigger price wars among second-tier foundries, accelerating industry consolidation.
