    摘要： A tunnel junction type Josephson device includes a pair of superconductor layers formed of a compound oxide superconductor material and an insulator layer formed between the pair of superconductor layers. The insulator layer is formed of a compound oxide which is composed of the same constituent elements as those of the compound oxide superconductor material of the superconductor layers but with an atomic ratio which does not present a superconductivity characteristics. In addition, the superconductor layers and the insulator layer are continuously formed while supplying oxygen.

    摘要： A method for forming an oxide superconductor thin film having different thickness portions, in a process for manufacturing a superconductor device, includes the step of forming an oxide superconductor thin film having a uniform thickness on a substrates. A portion of the oxide superconductor thin film is etch-removed so that the oxide superconductor thin film has a thin thickness portion. Preferably, before the etching, the oxide superconductor thin film is coated with a metal layer, and the oxide superconductor thin film and the metal layer are etched together by means of a physical dry etching process.
