Zusammenfassung:Disclosed herein are approaches for treating a film layer of a semiconductor device to modify an etch resistance of the film later. In one approach, a method may include forming a first film over a substrate base, depositing a second film over the first film, and introducing an inert species into the second film while the second film is deposited over the first film, wherein the inert species increases an etch-resistance of a first portion of the first film. The method may further include removing the second film by stopping deposition of the second film while continuing to introduce the inert species into the second film.
