TSMC is ramping up the construction of two chip factories in Arizona, a strategic move that could potentially lead to an increased production of Apple chips in the state. However, it's important to note that the latest cutting-edge chips will not be manufactured there initially. The Fab 21 facility in Phoenix marks TSMC's inaugural chip factory in Arizona, and the company aims to bring Fab 21 online ahead of schedule, despite concurrently building two other factories.
