Method of producing a wafer with an epitaxial quality layer and device with epitaxial quality layer

摘要

A method of making a wafer is provided. A first semiconductor film is formed onto a semiconductor substrate. An epitaxial film is formed onto an epitaxial wafer. The epitaxial wafer is placed with the epitaxial film on the first semiconductor film. The epitaxial film is debonded from the EPI wafer. The epitaxial film is bonded to the first semiconductor film.
