Abstract

1,016,999. Germanium semi-conductors. STANDARD TELEPHONES & CABLES Ltd. Nov. 9, 1964, No. 45543/64. Heading H1K. Germanium semi-conductor devices are made by forming a plurality of devices on or in one major surface of a germanium slice, depositing a layer of gold on the other major surface, scribing said other surface, alloying said layer to said slice and breaking the slice into individual devices. The layer of gold may be formed by evaporation or electroplating. The gold may be doped with Sb, As, Ga or A1 so that it forms an ohmic contact with the Ge device according to its conductivity type. The layer of gold is ductile until it is alloyed then it is brittle.
