Abstract:
A method for manufacturing a semiconductor device having an SiC-IGBT and an SiC-MOSFET in a single semiconductor chip, including forming a second conductive-type SiC base layer on a substrate, and selectively implanting first and second conductive-type impurities into surfaces of the substrate and base layer to form a collector region, a channel region in a surficial portion of the SiC base layer, and an emitter region in a surficial portion of the channel region, the emitter region serving also as a source region of the SiC-MOSFET.

Claim (Index 8):
The semiconductor device according to  claim 1 , wherein\n a part of the channel region is disposed on the side of the second surface of the SiC base layer with respect to the channel contact region, and the channel contact region faces one collector region through the part of the channel region.
