Apple plans to start using American-made processors after opening new state-of-the-art chip manufacturing plant in Phoenix, Arizona reports The Verge.

For customers, which also include AMD and NVIDIA, the new plant means more reliable chip supply and faster production times. TSMC, the plant’s owner, also said it will start construction on a second plant in Phoenix next year, which will increase annual production.

“These chips will power iPhones and MacBooks, as Tim Cook can attest,” President Joe Biden said at an event outside the Arizona factory on Tuesday. “Apple had to buy all the advanced chips from overseas. Now we’re going to do more of their supply chain here at home.”

Biden and Apple CEO Tim Cook were present in north Phoenix for the “tool-in” ceremony for the TSMC plant, which marked the arrival of production equipment at the first facility.

TSMC is a dedicated foundry, meaning it builds the chips designed by other companies. Apple, AMD and NVIDIA are among its largest customers, and even Intel relies on TSMC to make the most advanced processors.

The first factory in Phoenix will produce 4nm processors, the production of which is planned to start in 2024. The second factory will be launched in 2026 and will produce 3nm chips, which are the smallest and most complex processors in production today.

In total, TSMC said it will invest $40 billion in its Arizona facility, one of the largest foreign direct investments ever made in U.S. manufacturing. By 2026, the two factories will produce more than 600,000 wafers annually, which White House officials say will be enough to meet all U.S. demand for modern chips.
