Abstract
1360213 Semi-conductor devices JOSEPH LUCAS (INDUSTRIES) Ltd 16 Dec 1971 [30 Dec 1970] 61746/70 Heading H1K A semi-conductor body 11 having on one surface 11a at least one Al contact area 13 has on its opposite surface 11b successively deposited layers of Al 14, Cr, Ti or Mo 15, Ni 16 and a metal, such as Au 17, relatively resistant to oxidation. The layer 17 is then soldered, e.g. using a Pb-based solder 18, to a heat sink 12, e.g. of Cu. The layers 14-17 may be deposited by evaporation or sputtering. For a planar power transistor separate Al emitter and base contacts are provided on the surface 11a, the collector being contacted via the layers on the surface 11b.
