EU bureaucrats are too busy trying to keep the welfare/pension system from collapsing, defeating Russia, supporting Ukraine, managing the fossil fuels energy shortages, figuring out how to nerf Chinese EVs while supporting domestic car companies, and restricting social media free speech to make sure the "far right" don't win elections.
So of course, semiconductor manufacturing sovereignty is very low on their priority list.
That's what bureaucrats are supposed to be doing BTW.
