Abstract
A semiconductor device includes a transistor, a first diode, and a second diode. A collector of the transistor and a cathode of the first diode are electrically connected. The collector of the transistor and a cathode of the second diode are electrically connected, and an emitter of the transistor and an anode of the second diode are electrically connected. The first diode and the second diode are formed in an identical substrate. Thereby, the semiconductor device can be produced in a smaller size and in less steps.
