Abstract:
A semiconductor device includes: an active area including a drift layer of a first conductivity type; and a voltage blocking area arranged around the active area and including an field relaxation region having a second conductivity type, being provided in an upper portion of the drift layer, wherein a depth of the field relaxation region decreases toward outside, and a spatial-modulation portion is provided at an outer end of the field relaxation region.

Claim (Index 9):
The semiconductor device of  claim 1 , wherein the field relaxation region includes:\n a first electric-field relaxation-layer having the second conductivity type provided in an upper portion of the drift layer and having a spatial-modulation portion at an outer end of the first electric-field relaxation-layer; and a second electric-field relaxation-layer having the second conductivity type and having an impurity concentration lower than that of the first electric-field relaxation-layer, provided on an upper surface of the drift layer to an outer side of the first electric-field relaxation-layer so as to be in contact with the upper surface of the first electric-field relaxation-layer and having a spatial-modulation portion provided on an outer end of the second electric-field relaxation-layer.
