摘要:
A method for selective oxidation of silicon containing materials in a semiconductor device is disclosed and claimed. In one aspect, a rapid thermal processing apparatus is used to selectively oxidize a substrate by in-situ steam generation at high pressure in a hydrogen rich atmosphere. Other materials, such as metals and barrier layers, in the substrate are not oxidized.
