Claims
- 1. A semiconductor device having a semiconductor layer with a current path portion extending substantially from a first electrode to a second electrode of said device through which a main current flows, said semiconductor layer being structured so that a carrier lifetime in said semiconductor layer is different between substantially all of said current path portion of said semiconductor layer serving as a path for most of said main current and a remaining portion of said semiconductor layer.
- 2. A semiconductor device having a semiconductor layer with a current path portion, serving as a path for most of a main current, extending substantially from a first electrode to a second electrode of said device through which said main current flows, said semiconductor layer being structured so that a carrier lifetime in said semiconductor layer is different between at least a part of said current path portion of said semiconductor layer and a remaining portion of said semiconductor layer, wherein said semiconductor layer is structured so that the carrier lifetime in said semiconductor layer is different between a part of said current path portion of said semiconductor layer and a remaining portion of said current path portion of said semiconductor layer.
