A process for producing high temperature superconductor (HTS) mini-filters or coils in which the high temperature superconductor films are deposited on a layer of CeOon a substrate results in higher yields of mini-filters or coils.

Process for making high temperature superconductor devices each having a line oriented in a spiral fashion

This invention relates generally to cryogenic devices and, more particularly, to cryogenic devices of very small size based on superconducting elements, low thermal transmission interconnects and low dissipated power semiconductor.

Cryogenic devices

This invention relates to multilayered superconductive composites, particularly to composites based on thallium-containing superconducting oxides, and their process of manufacture.

Multilayered composites and process of manufacture

An improved device for off-axis magnetron sputter deposition of inorganic oxide compounds having a sputter gun, target, substrate, gas flow means and enclosure chamber wherein the improvement comprises a hollow gas flow manifold positioned between the substrate and the target having at least one gas inlet and at least one outlet opening on the manifold, said outlet opening positioned to direct the gas flow away from the target and in the direction of the substrate, and a process for such deposition are disclosed.

High flow gas manifold for high rate, off-axis sputter deposition

This invention relates to a process of forming multilayered thallium-containing superconducting composites, wherein a first thallium-containing superconducting layer, an intermediate thallium-containing oxide layer and a second thallium-containing superconducting layer are successively deposited on a substrate by a vapor phase process by controlling the heating temperature, pressure of oxidizing gas and thallium vapor pressure during post-deposition annealing of the superconducting films.

Process of forming multilayered Tl-containing superconducting composites

In-situ process are provided for 1) depositing on a substrate a crystalline thin film of a high temperature superconducting oxide by exposing the back surface of the substrate, i.e., the surface of the substrate opposite the surface on which the thin film is deposited, to radiation from a direct radiant heat source, thereby heating the substrate to the desired growth temperature, and maintaining the radiation and thereby the desired growth temperature during the deposition of the thin film, and 2) depositing a crystalline thin film of high temperature superconducting oxides onto both the front and back surfaces of a substrate.

Process for depositing high temperature superconducting oxide thin films

An in-situ process for preparing thin films which contain relatively volatile and involatile oxides is disclosed, in particular, crystalline thin films of oxides of conductors, superconductors or ferroelectric materials, wherein separate sources of the relatively volatile and involatile oxides during depositon of the thin film are employed.
