Abstract:
1. A semiconductor device comprising: a SiC layer of a first conductivity type having a hexagonal crystal structure; a first semiconductor region of a second conductivity type provided in a surface of the SiC layer; a second semiconductor region of the first conductivity type selectively provided in a surface of the first semiconductor region; a third semiconductor region of the second conductivity type selectively provided in the surface of the first semiconductor region adjacent to the second semiconductor region; a first conductive layer of the first conductivity type provided on the second semiconductor region; and a second conductive layer of the second conductivity type provided on the third semiconductor region, the second semiconductor region including SiC of a cubic crystal structure in a portion in contact with the first conductive layer in a case where the first conductivity type is P-type, and the third semiconductor region including SiC of a cubic crystal structure in a portion in contact with the second conductive layer in a case where the second conductivity type is P-type.
