Abstract
Methods for selectively depositing silicon oxycarbide (SiOC) thin films on a dielectric surface of a substrate relative to a metal surface without generating significant overhangs of SiOC on the metal surface are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a silicon precursor, a first Ar and Hplasma, a second Ar plasma and an etchant.
