摘要： A light activated thyristor with high dv/dt capability is provided by disposing first and second thyristors, one a primary and the other a pilot thyristor, in a semiconductor body having first and second major surface. The two thyristors have common first emitter, first base, and second base regions, and have spaced apart second emitter regions adjoining the second major surface of the body. The second emitter region of the second thyristor consists of first and second portions, first portion abutting the second base region of the second thyristor to create a ratarded electrical field. An exposed portion of the second major surface at the second emitter region of the second thyristor activates the second thyristor when electromagnetic radiation of wavelengths corresponding substantially to the energy bandgap of the semiconductor body strikes this exposed portion. The cathode electrode makes ohmic contact with the second emitter region of the first thyristor, and the anode electrode makes ohmic contact with the common first emitter regions. A floating contact also makes ohmic contact to the second emitter region of the second thyristor and the common second base region between the thyristors.

摘要： A novel structure of a high breakdown voltage semiconductor device has a pair of major surfaces on which a pair of main electrodes are formed and a PN junction formed between the pair of major surfaces with a side surface to which the PN junction is exposed being covered with a passivation material. An auxiliary electrode of a conductive member is provided, which is disposed externally of the peripheral edge of the major surface of the semiconductor substrate, and which contacts to the passivation material and is electrically connected to the main electrode. When a voltage for reverse biasing the PN junction is applied between the pair of main electrodes, ions in the passivation material are collected by an electric field established in the passivation material so that the deterioration of the breakdown on the surface of the semiconductor substrate is prevented.

摘要： A multi-emitter type semiconductor device, namely, a semiconductor device having an arrangement in which a majority of emitter regions are divided by a gate region and surrounded thereby. In the semiconductor device, a member adapted to apply an external control signal to a gate electrode takes the form of a closed-loop shape and the majority of emitter regions are arranged on both sides of the loop. This arrangement ensures that the individual emitter regions, even when the number of the emitter regions is increased to a great extent, can be applied with a uniform control signal, thereby preventing degradation of the turn-off characteristics.
