TSMC Advanced Packaging Fabs (AP7/Chiayi)

Dedicated CoWoS capacity buildout

TSMC's dedicated advanced-packaging fabs — including the Chiayi AP7 site and Taichung/Zhunan lines — are the physical capacity behind CoWoS output, which TSMC has repeatedly doubled to chase NVIDIA/AMD AI demand. CoWoS wafer-equivalent capacity, not front-end wafers, has been the true 2024-2026 AI bottleneck.

Constraint

CoWoS capacity = AI bottleneck

Site

Chiayi AP7, Taichung
