TSMC has enough room in Arizona to keep building for the next ten years. That’s the word from Chairman and CEO Dr. C.C. Wei, who confirmed during a recent earnings call that the company’s two land parcels in north Phoenix, totaling more than 2,000 acres, will accommodate its expansion plans through the mid-2030s.
The Arizona footprint takes shape
TSMC’s Arizona story has two chapters, measured in dirt. The original site covers roughly 1,100 acres, where the company’s first American fab has been running high-volume production since late 2024 with more than 3,000 employees on site.
Then came the sequel. In January 2026, TSMC picked up an additional 902 acres nearby for $197.25 million, nearly doubling its land holdings in the Phoenix metro area.
Wei’s confirmation that these combined parcels will suffice for a decade suggests the company has already mapped out a multi-phase buildout. The vision is what TSMC calls a “gigafab cluster,” a sprawling complex that would include multiple advanced fabrication plants, packaging facilities, and a dedicated R&D center.
