Sometimes the fab location might be older but the fab itself might have gone through much retooling throughout the years. I doubt the TI fabs in Sherman and Dallas in 1965/1966 are running all the same equipment as back then.
There are a lot of interesting fabs in the US making some pretty bleeding edge products, but often not digital microprocessor chips. A lot of the more bleeding edge are analog/RF kind of stuff, especially GaN and GaAs stuff.
