TSMC’s N2 wafers face a structural bottleneck and a 48-month capacity lead time
tengyanAI · x · 2026-07-24
A thread argues that TSMC effectively owns every N2 wafer coming off mass production, creating a structural bottleneck.
- With demand tightening against an estimated 48-month capacity lead time, there is little room for supply to loosen quickly.
- The physical process may be getting harder too: GAA transistors at N2 require tighter dimensional tolerances than N3, which means more metrology steps and more process-control passes per wafer.
