Patent ID: 7534702

Claim:
A method for manufacturing a semiconductor device comprising the steps of: forming a peel layer over a substrate having an insulating surface; forming a layer including at least first, second, and third portions over the peel layer, the third portion being interposed between the first portion and the second portion; forming first and second openings reaching the peel layer in each of the first and second portions; forming a material body over the third portion interposed between the first portion and the second portion; introducing an etching material in the first and second openings; selectively removing the peel layer by the etching material wherein a portion of the peel layer remains without being etched, and the material body and the third portion overlap said portion, and at least one of the first portion and the second portion does not overlap with any remaining portion of the peel layer; and separating the first portion and the second portion from the substrate having the insulating surface and the material body.
