TSMC’s U.S. Facility Capacities Fully Booked Despite Ongoing Expansion

• March 23, 2026

Taiwan Semiconductor Manufacturing Company (TSMC) continues to see high demand for its manufacturing capabilities in the United States, with all production capacities in Arizona fully reserved. This development comes amid efforts to boost domestic semiconductor production in the country.

Currently, TSMC operates one facility in Arizona that has been launched, while a second is nearing operational status. Moreover, a third factory is in the construction phase, and three additional plants are planned for the future. Despite many of these facilities not yet being completed or operational, the total production capacity across all these sites has already been completely booked by customers.

Strong U.S. Support Drives Demand for Domestic Chip Manufacturing

The accelerated booking of TSMC’s U.S.-based wafer fabrication plants reflects growing industry and government support for onshore semiconductor manufacturing. Policies aimed at strengthening domestic chip production have created an environment where demand for local fabs outpaces supply, even before new factories come online.

This trend highlights the critical importance of securing manufacturing supply chains amid global uncertainties and geopolitical tensions affecting the semiconductor sector. TSMC’s aggressive expansion in Arizona is a strategic move to meet the surging requirements of key technology companies needing reliable access to advanced chips manufactured domestically.

While TSMC has not disclosed specific details regarding the capacity or types of chips to be produced, the full reservation of its planned facilities signals a robust market appetite. It also confirms the company’s commitment to supporting U.S. manufacturing capabilities as part of its global semiconductor ecosystem.

Overall, the situation underscores ongoing shifts in the semiconductor industry landscape, with U.S. investments played a vital role in ensuring resilience and sovereignty over critical technology manufacturing.

TSMC’s semiconductor production capacities in Arizona are entirely reserved, even as multiple new factories are still under development.
