Abstract
1,026,114. Printed circuits. SIEMENS & HALSKE A.G. Dee. 13, 1963 [Dec. 18, 1962], No. 49363/63. Heading H1R. In a circuit comprising components mounted on an insulating wafer, conductive paths and/or contacts are formed by a plurality of metal layers, the inner layer which contacts the wafer being made of Cr, Mg or chromiumnickel alloy and the outer layer, which is alloyed to an inner layer, being made of gold. The inner layer has a resistance of between 50 and 500 ohms per square, and the Au layer has a resistance of between 0À05 and 1 ohm par square; preferred values are 100 and 0À2 ohms per square, respectively. As shown, a circuit on an insulating wafer 1 comprises two capacitors of which dielectric layers-4, 5 and electrode layers 6, 7 are visible, resistors 3, a transistor 8, and a power source 9. Conductive paths and a contact 2 are formed by vapourdeposition in vacuo of an inner layer of Cr-Ni alloy, followed, with continuous or discontinuous transition, by deposition of an outer layer of Au; annealing may then be effected. The alloy layer of Cr-Ni with Au should not extend to either surface of the conductor. A plurality of alternate Cr-Ni and Au layers may be used.
