摘要： A field controlled thyristor is disclosed which comprises a first emitter region exposed to one main surface of a semiconductor substrate and having a first conductivity type, a second emitter region exposed to the other main surface of the substrate and having a second conductivity type, a base region connecting the first and the second emitter region, and a gate region provided in the base region. The gate region consists of a slab-like first portion disposed parallel to both the emitter and a second portion connecting the first slab-like portion with one of the main surfaces of the semiconductor substrate. The impurity concentration of the base region is higher in the portion of the base region nearer to the emitter region having the same conductivity type as that of the base region than in the portion of the base region nearer to the emitter region having the opposite conductivity type to that of the base region. The field controlled thyristor has a high forward blocking voltage gain (anode-cathode voltage/gate bias voltage), a large current rating, and a high switching power capability and its switching time is very short.

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 chaotic character evaluating apparatus includes a processor for predicting future variation in sequential data and a processing for determining a degree of accuracy of the prediction, a processor for predicting variation of the sequential data in reverse and a processor for determining a degree of accuracy of the prediction, and a processing for comparing the degrees of accuracy with each other. If the degrees of the accuracy differ from each other, the variation of the sequential data is determined to be attributable to chaos, while when the degrees of accuracy are substantially equal to each other, the variation in the sequential data is determined to be attributable to noise. Further, a control apparatus for generating a control value from a feedback signal output from an object under control and having chaotic components eliminated is realized. Thus, it is possible to easily and accurately determine whether variation in the sequential data is attributable to chaos or noise.

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.
