    Abstract: In an engine ignition system, an igniter for an ignition coil is connected to an ECU through a signal wire. The signal wire is grounded via the collector and the emitter of a bipolar transistor of an output circuit of the igniter. A constant current source outputs a current to the base of the bipolar transistor. Switching transistors are connected between the emitter and base of the bipolar transistor. When all the switching transistors are turned off, the bipolar transistor is turned on.

    Abstract: An IGBT having a buffer layer for shortening the turn-off time and for preventing the latching up is improved. The buffer layer of the present invention is not bare at the edge of a diced cross-section of the IGBT chip. According to this construction, a withstanding voltage between a semiconductor substrate and the buffer layer is lower than the withstand voltage of the pn junction at the edge of the diced cross-section. Therefore, the whole pn junction between the semiconductor substrate and the buffer layer, which has wide area, breaks down, as a result, energy caused by a negative voltage is absorbed, and the withstanding voltage against the negative voltage is improved.
