Abstract:
Provided is a method for manufacturing an SiC composite substrate  10  having a single-crystal SiC layer  12  on a polycrystalline SiC substrate  11 , wherein: the single-crystal SiC layer  12  is provided on one surface of a holding substrate  21  comprising Si, and a single-crystal SiC-layer carrier  14  is prepared; polycrystalline SiC is then accumulated on the single-crystal SiC layer  12  by a physical or chemical means, and an SiC laminate  15  is prepared in which the single-crystal SiC layer  12  and the polycrystalline SiC substrate  11  are laminated on the holding substrate  21 ; and the holding substrate  21  is then physically and/or chemically removed. With the present invention, an SiC composite substrate having a single-crystal. SiC layer with good crystallinity is obtained with a simple manufacturing process.

Claim (Index 5):
The method for manufacturing, an SiC composite substrate according to  claim 1 , wherein the single-crystal SiC layer is provided on the one surface of the holding substrate with an intermediate layer made of silicon oxide, silicon nitride or silicon oxynitride interposed therebetween.
