Abstract

1,029,116. Transistors. SIEMENS & HALSKE A.G. June 17, 1964 [June 19, 1963], No. 25018/64. Heading H1K. A germanium transistor in which the collector zone is of higher resistivity than the base zone and which is attached by its collector zone to a Fe-Ni-Co alloy mounting plate may have its performance impaired by back injection of minority carriers present as impurities in the alloy. To avoid this the invention proposes the use of an alloy in which chromium and manganese and Group III and Group V elements are present, if at all, only in insignificant amounts. In practise this is achieved by mixing highly pure iron, cobalt and nickel and alloying them by sintering and by taking precautions that the mounting plate does not become contaminated during assembly of the device: e.g. by attaching the alloy mounting plate, carrying the transistor, to its permanent mounting only after the latter has been provided with its lead-out wires so that the alloy plate is not exposed to the high temperature and contaminating environment used in lead-attachment. The drawing (not shown) depicts such a transistor attached by a layer of gold alloyed both to the indium-doped collector and to the Fe-Ni-Co plate and with the antimony doped base and an aluminium alloyed emitter contact formed in a mesa on the collector.
