That's not so easy. The equipment in those older American fabs that were closed is no where near able to do anything current for the lithography required by today's chips.
Also, if the work was offshored decades ago, likely the infrastructure of the plant was gutted and what's left is an empty shell of a building.
Now for plants that are still operational, most have some relatively recent lithography that isn't cutting edge but can create a serviceable chip design for most types of electronic semiconductor needs. It might not run as fast, it might cost more due to fewer chips per silicon wafer, and it might be barebones on some features, but should be functional and workable.
Working in the industry, we have everything we need to make it happen. We need manufacturers to want to go back to US made chips.
While I agree old businesses aren't ready to just fire back up and start cranking out 90s technology, I absolutely agree we have the engineering skill and labor talent to make our own stuff. We absolutely need to do so ASAP.
Making 1 copycat part is probably not too hard, but making 10,000 of them in a year and making a profit.. that's hard on another level. Supply chains, tolerancing, labor, manufacturing equipment payoff, etc. Good people cost money, and they add up fast.
Admittedly, it is quite difficult. It takes some really knowledge engineers to design a chip from the ground up. The other difficulty is having the tooling and infrastructure. The lack of chips is also interesting. EV inventory has increased yoy and sales decreased. whereas trucks/suvs is inversely proportional. How are EVs sitting around lots but we can't find a chip for a truck? Also, look at chip factory outputs and static inventory. You may be surprised
