Taiwan Semiconductor Adding Another $100B to Phoenix Chip Making Effort

Taiwan Semiconductor Manufacturing Co. (TSMC) plans to spend an extra $100 billion to grow its U.S. business. The company says that money will likely help add four new fabrication plants in Arizona, which would make some of the world’s most advanced computer chips, 2-nanometer and smaller.

Those new factories would be added to TSMC’s big Arizona project in the North Valley. The company has already announced a $165 billion expansion that includes six chip plants, two advanced packaging facilities and a research and development center. The site is south of Loop 303 and west of Interstate 17. All together, the company’s total promised investment in U.S. chipmaking now looks like roughly $265 billion.

TSMC makes chips used by big-name companies like Nvidia and Apple. The company says the big push is happening because more and more people and businesses want AI, and AI needs powerful computer chips.

Earlier this year, TSMC paid nearly $200 million for land south of its sprawling campus near 43rd Avenue and Dove Valley Road in northwest Phoenix.
