Abstract: 985,667. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. June 8, 1961 [June 8, 1960], No. 20660/61. Heading H1K. A semi-conductor device is produced by alloying to a semi-conductor body two pills each containing about one impurity so as to produce two similar PN junctions and then destroying at least one of the junctions by passing reverse currents through it to provide an effective non-rectifying connection. Fig. 2 shows a P-type germanium body 1 to which are alloyed two pellets 2 and 3 each containing lead, gallium and antimony. Heat treatment results in the provision of N-type zone 4 by diffusion of antimony, and a P-type recrystallized zone 7. An electric pulse is then applied between the connection to the two pellets one PN junction thus being biased forwardly and the other in reverse. On breakdown of the reverse biased PN junction, the junction is destroyed to provide an ohmic contact to the diffused N-type zone 4. The process may be used to provide a post alloy diffused base transistor of mesa type and enables the same type of pellet to be used for both the emitter and base connections.
