Abstract
727,252. Semiconductor devices. STANDARD TELEPHONES & CABLES, Ltd. April 17, 1953 [April 25, 1952], No. 10456/52. Class 37. A semi-conductor device is manufactured by mounting the semi-conductor body on a metal plate, arranging a metal wire loop substantially parallel to the plate to form a skeleton mould and such that an electrode mounted on the loop contacts the surface of the body, and filling the skeleton mould with a liquid polymerizable insulating compound such as " Araldite " (Registered Trade Mark) to form a solid mass embodying the semi-conductor and the electrode. Fig. 7 shows the metal plate 2 fixed to wires 3, 4, which are fixed to a nickel ring 13. Terminal wires 5 and 6, also fixed to ring 13, are held together by a glass bead 7 and their ends are bent round in two semicircles to form the skeleton mould over plate 2. Two point contact electrodes 9, 10 are welded to wires 5 and 6 and are arranged to contact the surface of the germanium body 11, forming a transistor. After filling the mould with the insulating liquid which is polymerised, the wires 3, 4, 5 and 6 are cut away from ring 13 to provide a transistor as shown in Fig. 1. Alternatively, one of the contacts 9, 10 may be connected to the semi-conductor body by a conducting cement such as that described in Specification 716,243, [Group IV (a)]. The arrangement may comprise an additional electrode, or only a single point contact to provide a rectifier. The insulating material may consist of " Araldite " or a mixture of " Araldite " and alumina, reference being made to Specifications 518,057, 579,698, [both in Group IV], 629,111, 630,647, 630,663, [all in Group IV (a)], and 708,054.
