Abstract:
A silicon carbide semiconductor device includes: a drift layer in contact with a first main surface and having a first conductivity type; a body region located in the drift layer, in contact with the first main surface, and having a second conductivity type; and a protruding portion having the second conductivity type and connected to a bottom of the body region. A manufacturing method includes forming, in the drift layer of a silicon carbide substrate, by ion implantation, the body region, the protruding portion, a JTE region, and at least one guard ring region, each having the second conductivity type.

Claim (Index 10):
The method of manufacturing a silicon carbide semiconductor device according to  claim 8 , wherein\n the silicon carbide semiconductor device further includes a plurality of cells, each of the plurality of cells including the second impurity region and the third impurity region, and in the forming, the third impurity region is formed such that the plurality of cells have a same concentration profile of the impurity of the second conductivity type in the third impurity region along a depth direction from the first main surface.
