TSMC Begins U.S. Production of Advanced 4nm Chips at Arizona Facility

The $65 billion investment marks a milestone in U.S. semiconductor manufacturing, with production quality matching TSMC's Taiwan plants.

TSMC's Fab 21 in Arizona has started producing 4nm chips for major U.S. customers, including Apple and AMD, marking the first time such advanced chips are made on American soil.
The Arizona facility is part of a $65 billion investment to build three semiconductor fabs by 2030, supported by $6.6 billion in grants and $5 billion in loan guarantees from the CHIPS and Science Act.
The first phase of Fab 21 is operational, producing 10,000 wafers per month, with future phases set to manufacture 3nm and 2nm chips using cutting-edge technology.
The project is expected to generate over 20,000 jobs in Arizona and strengthen the U.S. semiconductor supply chain, with partnerships in workforce development involving local universities and community colleges.
TSMC's Arizona fabs are producing chips for high-profile products like Apple's A16 processors and AMD's Ryzen 9000 CPUs, a significant step toward the U.S. goal of producing 20% of the world's advanced logic chips by 2030.
