Beschreibung
Zusammenfassung:	A method for manufacturing a semiconductor substrate according to the present invention includes preparing a seed substrate containing a semiconductor material, forming an ion implanted layer at a certain depth from a front surface of a main surface of the seed substrate by implanting ions into the seed substrate, growing a semiconductor layer on the main surface of the seed substrate with a vapor-phase synthesis method, and separating a semiconductor substrate including the semiconductor layer and a part of the seed substrate by irradiating the front surface of the main surface of at least any of the semiconductor layer and the seed substrate with light.
