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 16):
The semiconductor device according to  claim 1 , further comprising an emitter electrode is in contact with the first surface of the SiC base layer, the emitter electrode connected to the emitter region and the channel contact region.
