Abstract
A semiconductor device includes a first semiconductor region that has an external profile including at least one corner, and that includes a semiconductor of a first conductivity type, and a first insulation region that surrounds an outer periphery of the first semiconductor region, and that includes an insulator that, at a corner portion corresponding to the corner, has a depth deeper than a depth at a location other than the corner portion. The semiconductor device further includes a second semiconductor region that surrounds an outer periphery of the first insulation region, and that includes a semiconductor of a second conductivity type, and a second insulation region that surrounds an outer periphery of the second semiconductor region, and that includes an insulator that is deeper than the depth of the first insulation region at the location other than the corner portion.
