Abstract:
1. A semiconductor device, comprising: a first semiconductor element layered on a second semiconductor element, an entire length of the first semiconductor element is adhered to and abutting the second semiconductor element, each of the first semiconductor element and the second semiconductor element comprising: the diode electrode and the collector electrode of the first semiconductor element are electrically connected to each other, and the diode electrode and the collector electrode of the second semiconductor element are electrically connected to each other, the emitter electrode of the first semiconductor element is electrically connected to the collector electrode of the second semiconductor element, so that upon alternately subjecting the first semiconductor element and the second semiconductor element to a switching operation, a current flows at a center side of the semiconductor substrate separated from the side face, a reverse current flows in the vicinity of the side face of the semiconductor substrate, when the semiconductor device is inoperative, and wherein the peripheral base region is formed at a corner of the semiconductor substrate.
