Claim:
1. A semiconductor device comprising: a semiconductor substrate; a first semiconductor region of a first conductivity type located in the semiconductor substrate; a second semiconductor region of a second conductivity type located in the semiconductor substrate and adjacent to the first semiconductor region at a boundary; a plurality of first contacts located in the first semiconductor region along the boundary and electrically connected to the first semiconductor region; and a plurality of second contacts located in the second semiconductor region along the boundary and electrically connected to the second semiconductor region, wherein the second contacts are not located in parts of the second semiconductor region on an opposite side to the first contacts across the boundary, the parts of the second semiconductor region being adjacent to the first contacts in a first direction substantially perpendicular to an arranging direction of the first and second contacts, and the first contacts are not located in parts of the first semiconductor region on an opposite side to the second contacts across the boundary, the parts of the first semiconductor region being adjacent to second contacts in the first direction.
