Will I get lots of rotten tomatoes telling, that this is a huge waste of money? Chips production is one thing, but the whole ecosystem matters. So these chips produced in Europe must be sent back to Asia for integration in final products. Or a miracle will happen and European Union will resurrect manufacturing? I doubt, because manufacturing means missing climate goals.
The robots that assemble the electronic circuits are also largely built in EU. (And, of course, in Japan, too.)
What made Apple to order their iPhone production from a Chinese company was not the availability of relevant hardware elsewhere; certainly the US has it. It was the nimbleness of that company, the willingness to move fast and make things available fast. Paradoxically, less red tape and less corporate shenanigans. Cheap labor? Maybe, but it did not appear to be the major factor, and wages at Foxconn were / are not as low, by EU standards even.
And this is compared to US; in Germany, things would be even slower, to say nothing of France (which is a real industrial powerhouse nevertheless).
