FASTER, PLEASE: TSMC’s Arizona Fab 21 is already making 4nm chips — yield and quality reportedly on par with Taiwan fabs.

TSMC has started producing chips at its Fab 21 near Phoenix, Arizona, using its 4nm-class process technology, Commerce Secretary Gina Raimondo told Reuters. This marks the first time such a cutting-edge production node has been manufactured in the United States. The confirmation from a high-ranking official comes months after the first unofficial information emerged that the fab was mass-producing chips for Apple.

“For the first time ever in our country’s history, we are making leading-edge 4nm chips on American soil, American workers — on par in yield and quality with Taiwan,” Raimondo told Reuters.
