ABSTRACT:
A semiconductor layer formed on one surface of a substrate is irradiated with light from the other surface of the substrate to thermally decompose part of a region of the semiconductor layer in contact with the substrate, thereby forming a thermally decomposed layer. Thereafter, the thermally decomposed layer is removed with the substrate kept bonded with the semiconductor layer.
