Abstract

The present disclosure describes a method of forming low thermal budget dielectrics in semiconductor devices. The method includes forming, on a substrate, first and second fin structures with an opening in between, filling the opening with a flowable isolation material, treating the flowable isolation material with a plasma, and removing a portion of the plasma-treated flowable isolation material between the first and second fin structures.
