Abstract

1,022,366. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Aug. 21, 1964 [Aug. 26, 1963], No. 33754/63. Heading H1K. A semi-conductor device has all its external electrodes, each consisting of a metallic contact carrying a layer of solder, disposed on the same plane face of a semi-conductor body. Transistors of this type are made in multiple on a common slice, part of which is shown in Fig. 1 of the Provisional drawings. The slice may be of N-type silicon and the base and emitter zones made by standard oxide masking and diffusion techniques. Aluminium is deposited over the oxide film to contact the collector, base and emitter zones through etched apertures 20, 19, 18, respectively. The oxide surface is then etched free of aluminium. A film grading from chromium beneath to gold above is vapour deposited over the entire surface and then reduced by etching to form contacts 20, 21, 22 which are next coated with solder. The transistor is soldered contacts downwards on a glass substrate carrying similar films aligned with the contacts. The substrate, alternatively of ceramic, oxidized silicon, mica, or plastics, may mount several such devices and other circuit elements. An apertured template may be used to facilitate registration of the device contacts with the films on the substrate. To facilitate accurate positioning of the contacts in relation to the wafer edge an N-type grid pattern is diffused into the slice simultaneously with the emitter formation and individual dice subsequently broken from the slice along the diffused lines. If desired, the aluminium contacts may be dispensed with and a gold, aluminium or plated nickel film used in place of the graded film. Contact may be made with the films on the substrate by thermo-compression bonding, bonding by radiation through the substrate if it is transparent, or by silverloaded epoxy resin instead of .by soldering. The device may finally be protected by a coating of glaze or resin.
