Quite a lot, but still incomparable to doing it from scratch. FAB require very unique equipment, not used in any other industry. Like water filtration plants that can make ultra pure deionised water in tenths of cubic metres per hour, process gas recycling plants, industry specific automation equipment, etc

Even a nineties tech level, a FAB still costs a megaton of money.

The most unique proposition here is that a prospect of getting an actual FAB with a lot of automation, and not a laboratory coaxed into manufacturing role is within the grasp. You can't have that anywhere else in the world.
