Taiwan Semiconductor Manufacturing Co (TSMC) has started producing four-nanometre chips for U.S. customers in Arizona, as confirmed by Commerce Secretary Gina Raimondo.
This development is part of the Biden administration’s semiconductor strategy, aided by a US$6.6 billion grant to TSMC's U.S. unit.
Raimondo emphasized that this marks the first time advanced chips are manufactured on American soil, matching Taiwan's quality and yield.
TSMC is also set to produce superior two-nanometer technology at a second fab in Arizona, expected to commence production by 2028.
The U.S. aims to manufacture 20% of the world’s leading-edge logic chips by 2030, a drastic increase from zero percent.
