Abstract
Various methods of manufacturing, including oxide film manufacturing, are provided. In one aspect, a method of fabricating an oxide film is provided that includes forming a trench in a semiconductor substrate and exposing the substrate to an oxidizing atmosphere containing oxygen but substantially no chlorine. The substrate is heated to react a surface of the trench with the oxidizing atmosphere to form the oxide film thereon. Chlorine induced oxide-silicon interface voids may be eliminated.
