Abstract:
A silicon carbide semiconductor device includes: n type regions formed on a surface of the n− type epitaxial layer; p type body regions formed at positions deeper than the n type regions; p− type channel regions each reaching the p type body region; and n++ type source regions formed toward the p type body region from the front surface side of the epitaxial layer, and the p− type channel regions and the n++ type source regions are formed at a planar position where the n type region remains between the p− type channel region and the n++ type source region, and out of boundary surfaces which are formed between the p− type channel region and the n type regions, the boundary surface on an outer peripheral side is positioned inside an outer peripheral surface  116 a  of the p type body region as viewed in a plan view.

Claim (Index 6):
The method according to  claim 2 , wherein the forming the gate electrode comprises forming an end portion of the gate electrode on the epitaxial layer of the first conductive type which remains between the channel region of the second conductive type and the second semiconductor region of the first conductive type as viewed in a plan view.
