Agreed.It's an international business. The big photolithography companies are Dutch (ASML) and Japanese (Nikon and Canon). However, a lot of the other equipment is American - Applied Materials and Lam Research. I think the big testing equipment companies include American companies. Not sure if Credence is still in business. I know Schlumberger is no longer in the automated test equipment business. I know they were a French company, but I took classes on semiconductor testing where the part-time instructor owned his own semiconductor testing support business and previously worked for Schlumberger at their Silicon Valley office.
I remember at many of my companies the wafers might be made one place but the cutting and packaging at another place. Packaging is mostly in Asia these days - Thailand, Malaysia, Singapore, etc.
Our prototype boards might be made locally, but they were very expensive. We had a guy in Richmond, California who would make boards and could do the expensive rework on those prototype boards. We must have paid him enough since he would hand-deliver stuff to us and liked coming over to talk shop. It was really weird too since he always came by wearing his ESD smock, even though nobody in our lab ever wore one. This is very different than production boards though, where I think that's overwhelmingly done in Asia now.
My contacts at Intel talk all day about EUV.
