    摘要: The GTO thyristor consists of a semiconductor substrate 11 of disc shape which has, in sequence, an emitter layer 16 on the cathode side, a second base layer 15, a first base layer 13,14, and an emitter layer 12 on the anode side. The emitter layer on the anode side is short-circuited by an emitter short-circuiting layer 13. The emitter layer 16 on the cathode side is divided into a plurality of radially extending elongate units, and the emitter layer 12 on the anode side is likewise divided into elongate units which are provided in the portions located at the areas of projection of the units of the layer 16 onto the anode side. The emitter short-circuiting layer 13 thus forms a plurality of wedge-shaped regions between the said areas of projection of the units of the layer 16. A thyristor of high current capacity and quick turn-off is thus achieved because the varying distance from the central lead wire 20 of the control electrode 18 is compensated by the varying width of the said wedge shaped regions of the emitter short circuit layer 13.

    摘要: A semiconductor device has a first semiconductor region (13,15,17) of a first conductivity type and a second semiconductor region (14) of a second conductivity type contacted by respective first and second electrodes (6,2). A semi-insulating layer (8) extends between the first and second electrodes (6,2) and there is a first insulating (4,7) between the semi-insulating layer (8) and the first semiconductor region (13,15,17). The sheet resistivity of the semi-insulating layer (8) 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 (19) covering the semi-insulating layer (8) and the first and second electrodes (6,2). Third semiconductor regions (16), with corresponding third electrodes (5) extend around, and are spaced from, the second semiconductor region (14). The third electrodes (5) extend over the parts of the first semiconductor region (13,15,17) adjacent the third semiconductor region (16) as this also improves the breakdown voltage. The second electrode (2) may also extend over the part of the first semiconductor region (13,15,17) adjacent the second semiconductor region (14) to cover the p-n junction therebetween.
