Abstract:
A silicon carbide semiconductor device includes a silicon carbide semiconductor substrate of a first conductivity type, a first silicon carbide layer of the first conductivity type, and an insulating film. In the silicon carbide semiconductor device, no fluorine or chlorine is detectable in the insulating film, at a boundary layer of the insulating film and the first silicon carbide layer, or at the surface of first silicon carbide layer where the insulating film is provided.

Claim (Index 1):
A silicon carbide semiconductor device, comprising:\n a silicon carbide semiconductor substrate of a first conductivity type, having a front surface; a first silicon carbide layer of the first conductivity type provided on the front surface of the substrate, the first silicon carbide layer having a first surface, and a second surface opposite to the first surface and facing the front surface of the substrate; and an insulating film selectively provided on the first surface of the first silicon carbide layer, the insulating film having a first surface, and a second surface opposite to the first surface and facing the first surface of the first silicon carbide layer, wherein no fluorine or chlorine is detectable at least one of\n in the insulating film, \n at a boundary between the first surface of the first silicon carbide layer and the second surface of the insulating film, and \n at the first surface of the first silicon carbide layer where the insulating film is provided.
