Abstract:
1. A method for manufacturing a semiconductor substrate, comprising: providing a first single crystal semiconductor layer over a first substrate; removing a native oxide film from a surface of the first single crystal semiconductor layer before providing a second single crystal semiconductor layer; providing the second single crystal semiconductor layer over the first single crystal semiconductor layer by a vapor-phase epitaxial growth method; attaching the first substrate and a second substrate to each other with an insulating film interposed therebetween so that the first single crystal semiconductor layer and the second single crystal semiconductor layer are provided between the first substrate and the second substrate; and separating the first substrate and the second substrate from each other at an interface between the first single crystal semiconductor layer and the second single crystal semiconductor layer so that the first single crystal semiconductor layer is provided over the first substrate, and so that the second single crystal semiconductor layer is provided over the second substrate.
