Patent ID: 7939426

Claim:
A method for manufacturing a semiconductor device, comprising: forming a plurality of first single crystal semiconductor films over a first glass substrate having an insulating surface with intervals between the plurality of first single crystal semiconductor films; forming a semiconductor film over the plurality of first single crystal semiconductor films; performing planarization treatment on the semiconductor film; forming a first insulating film over the first single crystal semiconductor films and the semiconductor film; superposing a plurality of single crystal semiconductor substrates in each of which a first fragile layer is formed at a predetermined depth on the first insulating film such that the semiconductor film is superimposed over the plurality of single crystal semiconductor substrates; forming a plurality of second single crystal semiconductor films over the first insulating film by separation at the first fragile layer through heat treatment; exposing the first single crystal semiconductor films by etching the first insulating film with the second single crystal semiconductor films used as masks; forming a third single crystal semiconductor film in stripes by vapor phase growth of the semiconductor film formed over the first single crystal semiconductor films and the second single crystal semiconductor films; forming a second fragile layer by introducing ions into the third single crystal semiconductor film; forming a second insulating film which functions as a bonding layer over the third single crystal semiconductor film; and fixing a part of the third single crystal semiconductor film to a second glass substrate with the second insulating film interposed therebetween by superposing the first glass substrate on the second glass substrate and separating the third single crystal semiconductor film at the second fragile layer through heat treatment.
