TSMC Accelerates Arizona Fab Expansion to Capture the AI 'Mega Trend'

TSMC CFO Wendell Huang announced an additional $100 billion investment in a CNBC interview, raising the total Arizona investment to $265 billion. The expansion reflects the view that structural AI-driven demand will continue for years, and the annual CAPEX guidance has also been raised to $60–64 billion.

On the process side, TSMC is rapidly converting 5nm equipment to 3nm to meet customer demand, while 2nm technology, which generated its first revenue in Q2, is expected to see full-scale growth starting in Q3. The Arizona Phase 1 (4nm) fab is already in operation.

Production costs at U.S. fabs are 4–5 times higher than in Taiwan, but CFO Huang said this will contribute to the long-term development of the U.S. semiconductor ecosystem. This investment includes both front-end wafer fabs and back-end advanced packaging fabs.

Meanwhile, China accounts for about 8% of total revenue, and TSMC stated it will continue supporting Chinese customers while complying with export regulations. Specialty technology areas, such as the image sensor joint venture with Sony, are also being cultivated as future growth drivers.
