Aren't rare earth metals used mainly for batteries, not chips ?

I guess people might be mixing up all the headlines of all the articles they did not read by this point.

Chips also need rare doping materials, plus an absurd level of purity for the silicon. The problems are the same no matter if we're talking about chips or batteries.
