1,242,898. Semi-conductor controlled rectifiers. GENERAL ELECTRIC CO. 7 Oct., 1968 [12 Oct., 1967], No. 47483/68. Heading H1K. In a shorted-emitter semi-conductor controlled rectifier part of the emitter region which is free of the emitter contact bears a separate control electrode. In the embodiment, Fig. 1, the emitter region 15 is apertured and the emitter electrode 17 extends over the entire region including the apertures save for a sector B of reduced thickness which carries aluminium wire control electrode 18. The emitter electrode short circuits the emitter region to adjacent region 14 via the apertures 142 and around its entire periphery. It may consist of evaporated aluminium, electroplated tungsten, or sputtered copper or gold. |
