Method of producing defect free epitaxially grown silicon.

摘要

A method for forming epitaxial grown silicon structure having substantially defect free outer surfaces and resulting structure is provided. A silicon substrate is provided, on which an epitaxial silicon crystal is grown. The outer surface layer of the silicon epitaxially grown silicon crystal will contain defective material which is removed by oxidation of the outer layer to silicon dioxide. This removes the defect containing outer layer, creating a new outer layer which is substantially defect free.
