1,100,834. Semi-conductor devices. DANFOSS A.S. 24 Feb., 1965 [24 Feb., 1964], No. 7998/65. Heading HIK. [Also in Divisions H2 and H3] The Specification describes semi-conductor devices which form a switching circuit comprising three star-connected junctionless non- rectifying solid state switches. In one arrangement (Fig. 3) the device has a layer of polycrystalline solid state material 10 evaporated on to a metal plate 9 to form the three switches 3a, 4a and 5a. In a modification (Fig. 4, not shown), a further electrode layer (15a, 15b) is evaporated on to the layer (14) of solid state switch material and is severed at (16) to provide two electrodes. The semi-conductor material consists predominantly of tellurium with the addition of elements of Groups IV and V of the Periodic Table, e.g. 67.5% tellurium, 25% arsenic and 7.5% germanium. The devices may be produced by evaporation on to a metal plate by sintering or by solidification of a molten alloy. |
