Abstract
Provided is a composite substrate which has a high-performance semiconductor layer. A composite substrate of the present invention comprises: a supporting substrate which is formed of an insulating material; a semiconductor layer which is formed of a single crystal semiconductor that is superposed on and joined to the supporting substrate; and interfacial inclusions which are present in the interface between the supporting substrate and the semiconductor layer at a density of 10atoms/cmor less, and which are formed of a metal element that is different from the constituent elements of the supporting substrate and the semiconductor layer.
