A rare look inside the TSMC Arizona plant making chips for Apple

TSMC's Arizona plants, with Apple as the first customer, result from CHIPS Act lobbying. These facilities mirror those in Taiwan, employing extreme secrecy and cutting-edge technology. Initially producing older-generation chips, TSMC plans to accelerate to chips for products about three generations old. The plants feature highly controlled clean rooms and complex processes, with each wafer taking months to produce and containing trillions of transistors. This marks a significant step in bringing advanced chip production to the US.
