Abstract
1365930 Vapour depositing super-conductors INTERNATIONAL BUSINESS MACHINES CORP 4 Oct 1971 [31 Dec 1970] 45501/71 Heading C7F [Also in Division H1] In a super-conductor device formation of hillocks, during manaufacture or use, on a superconducting metal film carrying a thin insulating layer and deposited on an insulating substrate is reduced by disposing a layer of material providing a low diffusivity interface for the component atoms of the film on the film or between it and the substrate. Exemplary film materials are silver for use with tin or lead layers, and gold for use with lead. A device of the tunneling type comprises an aligned but overlapping or an intersecting pair of 2000-20000 thick lead strips vacuum deposited on a quartz, sapphire, glass, or oxidized silicon substrate and spaced in the area or overlap by a 2-50A layer of lead oxide. Layers of gold 100-300 thick are disposed at the area of overlap on top of the upper lead strip and between the lower strip and the substrate and an insulated control conductor may be disposed over the area of overlap. The physical characteristics required of the hillock inhibiting material are discussed.
