TSMC to Elon Musk: There are no Shortcuts in Building Fabs!
What happened
TSMC announced expansion of 3nm capacity in Taiwan (H2 2027), Arizona (H2 2027), and Japan (2028), while planning to migrate some 5nm capacity to 3nm. This is driven by strong demand, high margins (>60%), and N3's dominant market position with zero merchant foundry competition. Neutral: Capacity additions are long-dated (2027-2028) and reflect structural demand, not an immediate supply shock.
