Abstract

A system and method of forming an oxide in the presence of a nitrogen-containing material. A substrate having a nitrogen-containing material on a surface is placed in a reaction chamber. An oxygen-containing gas, or an oxygen-containing gas and a hydrogen-containing gas are provided to the chamber and reacted in the chamber. The reactive gases are used to oxidize the surface of the substrate and displace the nitrogen-containing material from the interface.
