According to it's website, in May 2020, TSMC shared its plans to invest $12B in Phoenix, Arizona – building an advanced semiconductor manufacturing fabrication. In Dec 2022, the company announced its commitment to build a second fab in Phoenix, increasing its total investment to $40B. Then in April 2024, the U.S. Department of Commerce and TSMC Arizona announced up to US$6.6 billion in direct funding under the CHIPS and Science Act, fulfilling a goal to bring the most advanced chip manufacturing in the world to the US. TSMC also announced plans to build a third fab at TSMC Arizona. This third fab brings TSMC’s total U.S. investment to more than $65 billion, making this the largest foreign direct investment (FDI) in Arizona history, and the largest FDI in a greenfield project in U.S. history. Now with a third fab, TSMC Arizona will create approximately 6,000 jobs – and more than 20,000 accumulated unique construction jobs, as well as tens of thousands of indirect supplier jobs.
