Abstract
PURPOSE:To simply manufacture a Josephson element with high reproducibility by forming an insulating layer interposed between superconducting thin films made of group IIIa bariumcopper oxide by implanting oxygen ions into the surface of a first superconducting thin film. CONSTITUTION:A first superconducting thin film 2 is formed on a substrate 1, oxygen ions are implanted (as designated by arrows (a)) on the oxide thin film 2 to form an insulating layer 3 on its surface layer, and a second superconducting thin film 4 is so formed as to be superposed partly with the first superconducting thin film 2. The film 2 is formed in a strip state on the substrate 1, and the second film 2 is formed in a strip state on the substrate 1 to be partly superposed with the first film 2. The first and second films 2, 4 are formed of three types of materials, made of group IIIa metal and/or its oxide, barium and/or its oxide, and copper and/or its oxide. The purities of these materials are all 99.5% or more. The materials may be independently used, but alloy state (e.g., YBa2Cu3O7) may be used.
