Abstract
1,027,608. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 22, 1963, No. 46211/63. Addition to 1,026,164. Heading H1K. A mounting device for a semi-conductor wafer comprises a pair of cylindrical wires secured end-to-end in a bead of refractory insulating material without mutual contact, and a flat on one of the wires, closely adjacent to the bead, on which the wafer may be mounted. As shown, the ends of two cylindrical wires 3, 4, one of which has a pair of flats stamped on it near the end, are inserted in a bore in a glass bead 1 which is then fused to secure the wires. The flat 5 is adjacent to the bead 1 and a semiconductor diode wafer 7 is mounted on it by alloying using an intermediate gold preform. The ends of a fine gold wire 8 are joined to the upper face of the wafer 7 and to wire 3 by thermocompression bonding. The whole device may be encapsulated using, for example, an epoxy resin filled with alumina which increases the thermal conductivity of the device. Both wires may be provided with a pair of flats adjacent to the bead, and up to four diodes may be mounted on the two wires and connected in a variety of circuits. The semiconductor may be silicon or germanium or a compound and may also be joined to the wire by soldering or brazing or using a metal cement. The wires may be of " Kovar " (Registered Trade Mark), of " CuNiFe," or of platinum.
