In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a waferThe technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it The thermal oxidation process was pioneered in the late 1950s by Mohamed Atalla, who used it to fabricate the first metal–oxide–semiconductor (MOS .
