1,009,926. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 26, 1963 [Oct. 23, 1962], No. 37883/63. Heading H1K. A sealed semi-conductor device comprises a support, member having a flat supporting surface, a cylindrical member joined to the supporting member, a stack including a semiconductor wafer and springs disposed within the cylindrical member, and a member which screws into a thread at the top of the cylindrical member and compresses the springs to press the semi-conductor wafer against the supporting surface. This device is a modification of that disclosed in Specification 992,472. As shown, a conductive support member 12 comprises a support portion 14 and an annular flange 24 to which is joined a metal ring 26 provided with two circular projections 28, 30. A cylinder 32, internally threaded at its upper end, is welded to projection 28 by its flange 34, and a semiconductor unit 16, contact 22, conductors 23, 25, springs 40, 42 and washers 38, 39, 44 are arranged inside the cylinder and compressed by screwing an apertured plug 46 into the end of the cylinder. The spring pressure may be selected by the method described in the prior Specification. The device is sealed by welding flange 56 of a housing 50 to projection 30. Specification 910,016 is referred to. |
