Don't have semiconductors? News to me. I bet if you studied CS and you know any electronics engineers (who should be not too far from your department) they'll know wafer fabs in the US. I haven't been in uni for ages and I know like three fabs in Colorado where I don't even live.

In fact, there are like famous semiconductor companies that make their stuff in the US. Makes me suspect the rest of the list as similar doomsaying.
