As a point of interest, note that this won't be used for personal computer chips. When it opens in 2024, most such chips (at least those from TSMC) will be on 3 and 4 nm processes. The 5 nm chips from this plant will instead be used for high-demand automotive applications (e.g., self-driving and driver assistance systems) [1].
TSMC doesn't build any of its most advanced plants in the US; I believe those are (not surprisingly) confined to Taiwan. So while the chips built by the Arizona plant will of course be commercially important (as the article mentions, lots of products use chips with larger node sizes), don't expect the chips in your Apple devices to be made in the US anytime soon.
