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 4):
The method according to  claim 1 , wherein the forming the gate electrode comprises forming an end portion of the gate electrode on the second semiconductor region of the first conductive type as viewed in a plan view.
