Patent ID: 7508034

Claim:
A semiconductor device, comprising: a non-single-crystal silicon thin-film device manufactured from a non-single-crystal silicon thin film and a single-crystal silicon thin-film device manufactured from a single-crystal silicon thin film, wherein the non-single-crystal silicon thin-film device and the single-crystal silicon thin-film device are provided in different areas of an insulating substrate, wherein the non-single-crystal silicon thin-film is the first non-single-crystal silicon thin-film layer above the insulating substrate, and wherein the non-single-crystal silicon thin-film and the single-crystal silicon thin-film are each vertically separated from the insulating substrate by a space, or at least one other layer, such that a surface of the non-single-crystal silicon thin-film that is nearest to the insulating substrate and a surface of the single-crystal silicon thin-film that is nearest to the insulating substrate are at different heights above the insulating substrate.
