Abstract:
In a termination structure region, a first semiconductor layer of a first conductivity type, with an impurity concentration lower than that of a semiconductor substrate, is provided on the substrate of the first conductivity type. A second semiconductor layer of a second conductivity type is provided on a first side of the first semiconductor layer, opposite to a second side facing the substrate. Trenches penetrate the second semiconductor layer. At the first side in the first semiconductor layer, a first semiconductor region of the second conductivity type, with an impurity concentration higher than that of the second semiconductor layer, is provided at a side closer to an active region, contacting the second semiconductor layer. A second semiconductor region of the first conductivity type is provided in the second semiconductor layer, outside and adjacent to one of the trenches that is disposed at a farthest position from the active region.

Claim (Index 2):
The semiconductor device according to  claim 1 , further comprising\n a third semiconductor region of the second conductivity type provided in the first semiconductor layer, and contacting a side surface of the first semiconductor region in a lateral direction, the third semiconductor region being disposed under the plurality of trenches, and being spaced from the second semiconductor layer, the third semiconductor region having an impurity concentration lower than the impurity concentration of the first semiconductor region.
