摘要： To provide a method for manufacturing an SOI substrate provided with a semiconductor layer which can be used practically even when a substrate having a low heat-resistant temperature, such as a glass substrate or the like is used. The semiconductor layer is transferred to a supporting substrate by the steps of irradiating a semiconductor wafer with ions from one surface to form a damaged layer; forming an insulating layer over one surface of the semiconductor wafer; attaching one surface of the supporting substrate to the insulating layer formed over the semiconductor wafer and performing heat treatment to bond the supporting substrate to the semiconductor wafer; and performing separation at the damaged layer into the semiconductor wafer and the supporting substrate. The damaged layer remaining partially over the semiconductor layer is removed by wet etching and a surface of the semiconductor layer is irradiated with a laser beam.
