Patent ID: 7960262

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: forming a single-crystal semiconductor layer in a first region over a substrate; forming a non-single-crystal semiconductor layer in a second region over the substrate so that the non-single-crystal semiconductor layer is not overlapped with the single-crystal semiconductor layer; forming a cap film over one of the single-crystal semiconductor layer and the non-single-crystal semiconductor layer so that the cap film does not overlap the other of the single-crystal semiconductor layer and the non-single-crystal semiconductor layer; and applying a laser beam from above the cap film to irradiate the first region in which the non-single-crystal semiconductor layer in the second region is not overlapped with the single-crystal semiconductor layer and the second region, wherein, in the step of applying the laser beam, the non-single-crystal semiconductor layer and the single-crystal semiconductor layer are not overlapped with each other.
