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 14):
The method of manufacturing a silicon carbide semiconductor device according to  claim 8 , wherein\n in the forming, a dose amount of the impurity of the second conductivity type in the electric field relaxing region is not less than 0.5\u00d710 13  cm \u22122  and not more than 5\u00d710 13  cm \u22122 .
