    摘要: A semiconductor device includes an emitter region, a collector region provided directly under the emitter region, and a two-region base structure. The first base region is interposed between the emitter and collector regions, and the second base region supports the collector region. The aforementioned regions have a progressively higher impurity concentrations, with the collector region having an impurity concentration higher than that of the first base region, the second base region having an impurity concentration higher than that of the collector region, and the emitter region having an impurity concentration higher than that of the base region. Also included is a resistance region formed, in one embodiment, from a projecting end portion of one of the base layers. The projecting end portion of the base is fabricated so that both base portions contact one another in the resistance region, and consequently both base portions are of the same potential. Electrodes are also provided for ohmicly contacting the emitter, collector, and base regions. The two-region base structure enables the device to achieve a high resistance, and thus to achieve simultaneously a high breakdown voltage and a high frequency (speed) characteristic.

    摘要: A problem to be solved by the present invention is to eliminate variation in potential in a turn-off time period of each GTO element, and to stabilize a gate drawing current by surely performing the turn-off of the GTO element. In an inverter apparatus having a three-phase inverter configured to include paired GTO elements an inverter control portion has a simultaneous switching prevention function of delaying a turn-on operation of each of the GTO elements which correspond to phases other than a phase corresponding to an optional one of the GTO elements and also correspond to an electrode opposite to an electrode corresponding to the optional one of the GTO elements by a predetermined time in a case where a turn-on command signal for turning on each of the GTO elements is generated within a predetermined time period since the turn-off of the optional one of the GTO elements.

    摘要: According to the present invention, a MOSFET is formed of an n source, a p well, an n drain and a MOS gate electrode, a bipolar transistor is formed of an n emitter, a p base and an n collector formed in sequential order adjacent to the n drain. These transistors are formed by being merged with each other by the contact of n drain and the n emitter of the same conductivity type. Holes are injected into the drain of a voltage-driven type transistor comprised of the MOSFET from the bipolar transistor having a very small collector saturation resistance. With this, it is possible to give rise to conductivity modulation in the drain of the MOSFET, while the power dissipation of the voltage-driven type semiconductor device becomes very small.

    摘要: A semiconductor device has a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type contacted by respective first and second electrodes. A semi-insulating layer extends between the first and second electrodes and there is a first insulating layer between the semi-insulating layer and the first semiconductor region. The sheet resistivity of the semi-insulating layer varies, and this improves the high breakdown voltage of the p-n junction of the semiconductor device between the first and second semiconductor layers, by acting as a shield for charges included on a passivation insulation layer covering the semi-insulating layer and the first and second electrodes. Third semiconductor regions, with corresponding third electrodes, extend around, and are spaced from, the second semiconductor region. The third electrodes extend over the parts of the first semiconductor region adjacent the third semiconductor regions, and this also serve to improve the breakdown voltage. The second electrode may also extend over the part of the first semiconductor region adjacent the second semiconductor region to cover the p-n junction therebetween.

The emitter electrode extends on a passivation film covering the one principal surface of the substrate to terminate at a point on the second collector layer.
