Abstract
Disclosed are a superjunction semiconductor device and a method of manufacturing the same. More particularly, the superjunction semiconductor device includes at least one body region in a second corner region extending along the length direction in the same manner as a pillar, thereby promoting smooth current flow in a transition corner region and thus improving reverse recovery characteristics; and a method of manufacturing the superjunction semiconductor device.
