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 2):
The semiconductor device according to  claim 1 , wherein\n the collector region has a first surface extending along the second surface of the SiC base layer and a second surface extending along a thickness direction of the SiC base layer, and the SiC base layer includes a first region having a first impurity concentration in contact with the channel region and a second region having a second impurity concentration higher than the first impurity concentration and surrounding the collector region such that the second region is in contact with both the first surface and the second surface of the collector region, and the second region of the SiC base layer is independent from the drain region.
