Abstract
In a current-prioritized IGBT, a collector conductive layer is connected to one collector active region included in a collector region by a plurality of contacts. The number of contacts through which the collector conductive layer is connected to the one collector active region is larger than the number of contacts through which the emitter conductive layer is connected to one base active region included in a base region.
