Patent ID: 7829431

Claim:
A method for manufacturing a semiconductor device, comprising: doping a plurality of single-crystal semiconductor substrates with hydrogen to form an embrittlement layer in each of the plurality of single-crystal semiconductor substrates; bonding each of the plurality of single-crystal semiconductor substrates to a first substrate; removing a portion of each of the plurality of single-crystal semiconductor substrates at the embrittlement layer by performing heat treatment to form a plurality of single-crystal semiconductor layers over the first substrate; dividing the first substrate and the plurality of single-crystal semiconductor layers to form a plurality of pieces of single-crystal semiconductor, each of the plurality of pieces of single-crystal semiconductor including a piece of the first substrate; bonding a supporting substrate to each of the plurality of pieces of single-crystal semiconductor; separating at least a portion of the piece of the first substrate from each of the plurality of pieces of single-crystal semiconductor; bonding each of the plurality of pieces of single-crystal semiconductor to a second substrate having an insulating surface; and removing the supporting substrate from each of the plurality of pieces of single-crystal semiconductor.
