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 12):
A silicon carbide semiconductor device comprising:\n a silicon carbide layer; a drift layer of a first conductivity type provided within the silicon carbide layer; a plurality of well regions of a second conductivity type selectively provided in an upper layer part of the silicon carbide layer, the second conductivity type being different from the first conductivity type; a source region of the first conductivity type provided within each of the plurality of well regions; a JFET region serving as a part of the drift layer sandwiched between the plurality of well regions and reaching an upper surface of the silicon carbide layer; a channel region provided within each of the plurality of well regions and sandwiched between the source region and the JFET region; an insulating film provided on the silicon carbide layer and at least covering the JFET region; and an electrode provided on the JFET region via the insulating film, wherein the insulating film and the electrode include a region containing a different element that is different from elements constituting the insulating film and the electrode, and the region containing the different element is provided above the JFET region and is not provided above the channel region.
