Abstract

801,444. Transistors. STANDARD TELEPHONES & CABLES, Ltd. Sept. 5, 1956, No. 31527/57. Divided out of 801,442. Class 37. A method of fixing a lead to an electrode of a transistor comprises the steps of applying the lead to the electrode, passing a current between the lead and electrode so as to fuse the latter, pushing the lead into the molten electrode, cooling the electrode, applying a flux to the junction between the lead and the electrode, and then passing a further current to fuse the electrode to the lead. In one embodiment leads are fixed in this way to electrodes in the form of indium pellets 2, 3 which have been fused to opposite faces of an N-type germanium body 1 to form a PNP junction body by the method described in Specification 801,443. In an alternative embodiment the electrodes are lead or lead antimony pellets fused to a P-type body by the same method. It is possible to fix both leads in a single operation by using alternatingi currents passed between them via the semiconductor body. A base contact in the form of an open circle of gold-plated molybdenum, which is flash-plated with antimony if the body is N- type, is fused to the body about the indium pellet 2 by passing a current through it as described in Specification 801,442 from which the subjectmatter of the present Specification has been divided.
