Abstract

1,172,772. Semi-conductor devices. WESTINGHOUSE BRAKE ENGLISH ELECTRIC SEMI-CONDUCTORS Ltd. 10 July, 1968 [20 July, 1967], No. 33412/67. Heading H1K. In a multizone multi junction semi-conductor device an inner region is exposed through one or more perforations in an alloyed emitter zone, the exposed surface of the region being abraded. In an embodiment, a regularly perforated goldantimony annulus is alloyed to one surface of a silicon wafer already containing two parallel junctions. The surface exposed through the perforations is sand-blasted to enhance the carrier recombination rate and successive layers of nickel and gold then vapour deposited over the annulus (with the rest of the body waxmasked). The nickel-gold layer is then sintered at a temperature of less than 450‹ C. in a hydrogen atmosphere to increase its adhesion to the body. The layer makes ohmic contact to both the gold-antimony electrode and the exposed surface.
