TSMC’s American chipmaking plans grow $25bn more ambitious

TSMC makes about three-quarters of the world’s most cutting-edge computer chips. But even as it builds new factories (or fabs) in America and Japan, it has kept its most advanced production at home in Taiwan. Until now. On April 8th TSMC said that it intended to make “2-nanometre” chips, the current state of the art in chipmaking, at its planned fab in Arizona. It will also build a third factory in the state by 2030, on top of two already in the works. Its total American investments will rise from $40bn to $65bn. Uncle Sam will chip in another $6.6bn in grants and up to $5bn in loans.
