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 1):
A semiconductor device, comprising:\n an active region through which current flows; and a termination structure region disposed outside the active region and in which a termination structure is formed, wherein the termination structure region includes:\n a semiconductor substrate of a first conductivity type; \n a first semiconductor layer provided on a front surface of the semiconductor substrate, the first semiconductor layer having an impurity concentration lower than an impurity concentration of the semiconductor substrate; \n a second semiconductor layer of a second conductivity type provided on a first side of the first semiconductor layer, opposite to a second side thereof, said second side facing the semiconductor substrate; \n a plurality of trenches penetrating the second semiconductor layer; \n a first semiconductor region of the second conductivity type provided in the first semiconductor layer at said first side, the first semiconductor region being in contact with the second semiconductor layer, and being disposed at a side closer to the active region, the first semiconductor region having an impurity concentration higher than an impurity concentration of the second semiconductor layer; and \n a second semiconductor region of the first conductivity type provided in the second semiconductor layer, the second semiconductor region being disposed outside and adjacent to one of the plurality of trenches, the one of the plurality of trenches being disposed at a farthest position from the active region.
