Thanks to the Taiwan Semiconductor Manufacturing Co. plant just north of Phoenix, Arizona will receive a significant slice of Apple Inc.’s recent $500 billion U.S. commitment to invest in various plants throughout the country.

Apple’s recent announcement amounts to the largest such capital outlay in the tech company’s history. The plan calls for Apple to double the size of its U.S. Advanced Manufacturing Fund from $5 billion to $10 billion, which includes a multibillion-dollar commitment from Apple to produce advanced silicon in TSMC’s Fab 21 facility in Arizona.

Apple says it’s the largest customer at this state-of-the-art facility in north Phoenix, where mass production of Apple chips began last month. Apple committed to sourcing chips from the Arizona TSMC factory back in 2022.

Operations are expected to begin in 2028 at TSMC’s second Phoenix factory, which will produce 2—and 3-nanometer process technologies for Apple, AMD, Nvidia and Qualcomm.
