Abstract

Methods of performing a wet oxidation process on a silicon containing dielectric material filling within trenches or vias defined within a substrate are provided. In one embodiment, a method of forming a dielectric material on a substrate includes forming a dielectric material on a substrate by a flowable CVD process, curing the dielectric material disposed on the substrate, performing a wet oxidation process on the dielectric material disposed on the substrate, and forming an oxidized dielectric material on the substrate.
