Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chip manufacturer, revealed plans in March 2025 to invest an additional $100 billion to expand its semiconductor manufacturing complex in Phoenix, Arizona. The announcement was made jointly by TSMC CEO C.C. Wei and then-U.S. President Donald Trump at the White House, marking a historic boost for American semiconductor production.
This new investment builds on a previous $65 billion commitment by TSMC to establish advanced chip fabrication in the United States. Combined, TSMC’s total pledged investment in Arizona now reaches $165 billion, making it one of the largest foreign direct investments ever made in U.S. soil.
Under the expansion plan, TSMC intends to build three additional semiconductor fabrication plants, two cutting-edge packaging facilities, and a major research and development center. These new factories will double the footprint of TSMC’s Arizona operations, growing from three fabs to six, with the third new plant slated to produce cutting-edge 2-nanometer chips, the most advanced technology expected late in the decade.
This sizeable industrial and capital investment is projected to generate approximately 25,000 permanent jobs as well as over 40,000 construction and related roles during the build-out phase, supporting both skilled and non-skilled labor sectors in the region.
TSMC’s expanded footprint reflects broader U.S. policy goals to boost domestic semiconductor manufacturing capacity, reduce supply chain vulnerabilities, and maintain competitiveness in an increasingly technology-driven global economy. The expansion is also a strategic move by TSMC to better serve key American customers and avoid tariffs by producing locally.
Construction on the second plant is already underway as of early 2026, while plans for the additional fabs and R&D center are progressing. TSMC has also acquired an additional 900-acre site adjacent to its existing campus to facilitate the expanded industrial cluster.
The expansion underscores Arizona’s growing role as a center for high-tech manufacturing and highlights ongoing investment trends in critical industrial sectors tied to national infrastructure and economic security.
