Abstract:
A silicon carbide semiconductor device includes: an n-type drift layer 2 provided within an SiC layer  30;  a plurality of p-type well regions  3;  a JFET region JR serving as a part of the drift layer  2  sandwiched between the well regions  3;  and a gate insulating film  6  and a gate electrode  7  at least covering the JFET region JR. The gate insulating film  6  and the gate electrode  7  include a different-element-containing region  10  containing an element that is different from elements constituting the gate insulating film  6  and the gate electrode  7.

Claim (Index 14):
The silicon carbide semiconductor device according to  claim 12 , wherein\n the electrode is constituted of silicon, and includes any of phosphorus, arsenic, antimony, boron, and gallium as impurity dopant, and the different element is any of carbon, nitrogen, fluorine, sulfur, chlorine, selenium, bromine, and iodine.
