A feud is heating up between Arizona workers and the world’s leading chipmaker after the company claimed the US doesn’t have the skills to build its new factory::TSMC wants to bring in foreign reinforcements to get its Arizona factory running because it claims there aren’t enough qualified local workers.
No other chip production in the state?
Intel has several fabs in Chandler, AZ. They have down to 10 nm there, with 5nm being their best. So there definitely is a chunk of knowledge in the state.

Seems like semiconductors are kind of a big deal in and around Chandler which is presumably why TSMC chose there.
