Abstract
804,696. Transistors. SIEMENS & HALSKE A.G. Feb. 3, 1956 [Feb. 3, 1955], No. 3480/56. Class 37. In a transistor having alloyed emitter 2 and collector 3 electrodes on opposite sides of a semi-conductor wafer 1, the base electrode 4 consists of a solid noble metal, i.e. gold, silver, platinum, ruthenium, rhodium, palladium, osmium or iridium. In the example shown in Fig. 1, the base electrode is in the form of a ring surrounding the emitter, and may consist of a wire, or a stamping. Alternatively the base electrode may be combshaped, with the remaining electrodes arranged between the teeth, and it may contain a trace of acceptor or donor material to ensure good contact, or alloying elements such as silver or lead. Two base electrodes may be provided on opposite sides of the wafer.
