Mizuho lifts TSMC CoWoS capacity forecasts as server CPU demand surges - Investing.com

Mizuho Financial Group has raised its capacity forecasts for TSMC's CoWoS (Chip on Wafer on Substrate) technology due to surging demand for server CPUs. This adjustment reflects the ongoing expansion ... Read original →

TSMC’s CoWoS capacity hike signals a structural shift: advanced packaging is no longer auxiliary but central to AI-driven server CPU scaling. Upstream, EUV tool lead times exceed 18 months; downstream, HBM-CoWoS integration has become the new performance bottleneck. Although U.S. export controls haven’t explicitly targeted CoWoS, its tight coupling with AI accelerators may soon draw regulatory scrutiny, raising compliance costs for global customers. Samsung and Intel will likely counter by fast-tracking I-Cube and Foveros offerings to lure NVIDIA and AMD with alternative supply options. Over the next 12–24 months, CoWoS-class technologies will evolve from process enablers into strategic assets. TSMC’s yield leadership grants it a second moat in 3D integration—but geopolitical friction could compel hyperscalers to build redundant packaging capacity outside Taiwan, China.
