Patent ID: 7851332

Claim:
A method for manufacturing a semiconductor device including a semiconductor substrate comprising the steps of: arranging a plurality of single crystal semiconductor substrates in a tray; forming an insulating layer over the plurality of single crystal semiconductor substrates; forming a damaged region in each of the plurality of single crystal semiconductor substrates by irradiating the plurality of single crystal semiconductor substrates with ions; forming a bonding layer over the insulating layer; bonding each of the plurality of single crystal semiconductor substrates and a substrate having an insulating surface with the bonding layer interposed therebetween; separating the plurality of single crystal semiconductor substrates with a plurality of single crystal semiconductor layers left over the substrate having an insulating surface; and forming a depression in the substrate having an insulating surface, wherein the depression is formed between one of the plurality of single crystal semiconductor layers and another adjacent one of the plurality of single crystal semiconductor layers.
