1,060,397. Semi-conductor devices. PHILCO CORPORATION. Oct. 9, 1963 [Oct. 9, 1962], No. 39792/63. Heading H1K. A semi-conductor element is connected to a contact area of a thin film circuit by attaching the element to a metal lamina which overlaps it at least two edges and bonding at least the overlapping parts to the contact area. Typically silicon transistors or diodes are bonded at spaced intervals to a metal ribbon. The ribbon may be of gold doped with donor or acceptor so as to form an ohmic contact when bonded to the silicon by heating to the silicongold eutectic temperature or by soldering. Elements each with extending portions of ribbon, subdivided from this, are attached by spot welding, ultrasonically welding, thermocompression bonding, or soldering the extending portions to contact lands on a thin-film circuit, Fig. 2, formed by the method described in Specification 1,060,398. The elements are then connected into the circuit by thermocompression bonding gold or aluminium wires such as 18 to zones of the element and contact lands on the circuit. |
