Abstract

1,251,456. Semi-conductor devices. FERRANTI Ltd. 8 June, 1970 [12 June, 1969], No. 29974/69. Heading H1K. Ion migration from a plastics encapsulation 27 into a passivating layer 18 on a semi-conductor device such as a Si transistor 10 under the influence of an electric field associated with a reverse-biased p-n junction 19 is prevented by the provision of a metal shield 22 between the plastics encapsulation 27 and the passivating layer 18 where they overlie the junction 19. The shield 22 is at the same potential as one of the two semi-conductor regions defining the junction 19; thus in the embodiment it comprises an extension of the base electrode 22. The passivating layer 18 may be of silicon oxide containing phosphorus introduced during diffusion of the emitter region 17 while the plastics encapsulation 27 may be an epoxy resin, a silicone or polytetrafluorethylene.
