摘要： Disclosed is a field controlled thyristor in which a first semiconductor region of N.sup.+ -type, a second semiconductor region of N-type, third semiconductor regions of P-type, a fourth semiconductor region of N.sup.- -type and a fifth semiconductor region of P.sup.+ -type are formed in a semiconductor substrate having two main surfaces, the first, second and third semiconductor regions being exposed in the first main surface and the fifth semiconductor region being exposed in the second main surface; and the third semiconductor regions of P-type are spaced from each other by a predetermined spacing. The third semiconductor regions are connected with surface-exposed semiconductor regions exposed in the first main surface. The impurity concentration in the second semiconductor region decreases from the first semiconductor region toward the third semiconductor region so that a low forward voltage drop can be achieved along with a high reverse blocking voltage. Also disclosed is a method for forming the third semiconductor regions and the surface-exposed semiconductor regions through a diffusion process alone.

摘要： A switching control circuit includes a first field controlled thyristor having a gate and a cathode between which a backward bias voltage source and a second field controlled thyristor are connected in series. Conduction of the second field controlled thyristor is controlled by controlling a voltage applied across the gate and the cathode, thereby to control conduction of the first field controlled thyristor. A large load current can be positively and safely turned on and off by a relatively small control current or voltage.

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： An improvement in a semiconductor switching device is disclosed which comprises a semiconductor substrate of a first conductivity type, an anode region of a second conductivity type formed in the semiconductor substrate adjacent to a major surface thereof, a gate region of the second conductivity type formed a distance from the anode region, and a cathode region of the first conductivity type formed in the gate region and having a higher impurity concentration than the semiconductor substrate. A channel region is formed immediately below the cathode region thereby to directly contact the cathode region to the semiconductor substrate. A current path extending from the anode region to the cathode region through the semiconductor substrate is interrupted by a depletion layer produced in the vicinity of the channel region upon application of a reverse bias across a pn-junction formed between the gate region and the cathode region. When no reverse bias voltage is applied, the anode region, the semiconductor substrate and the gate region cooperate to function as a thyristor. The semiconductor switching device has a high dv/dt capability and is easily implemented in integrated circuits.

摘要： When communication is performed simultaneously with two moving bodies such as a satellite, an antenna construction in which a plurality of antennas do not become an obstacle to each other's communication and the direction (the azimuth angle and the elevation angle) adjusting mechanism thereof can be realized with a simple construction. The two antennas have another movable portion (a rotation mechanism with respect to the axis) independently, while sharing the direction adjusting mechanism for the azimuth angle and the elevation angle. The rotation axis of the rotation mechanism of each antenna faces the same direction on the same plane, and each rotation mechanism is separately arranged in an area defined by a plane obtained by extending the axis of the azimuth angle adjusting mechanism toward the axial direction of the elevation angle adjusting mechanism. The azimuth angle and the elevation angle of respective antennas can be separately adjusted by the rotation mechanism with respect to the axis, hence the antennas can be directed to the communication targets existing in the two different directions simultaneously from the reception point.
