Abstract
A method for fabricating an oxide superconducting device includes the steps of: forming a V-shaped groove on a substrate by a converging ion beam and forming a barrier with reduced superconductivity on the oxide superconducting thin-film on the groove to form a Josephson Junction, wherein the irradiation ion amount of the converging ion beam is varied according to the position of the beam within the groove in such a manner that an inclination angle of the inclined portion of the substrate is fixed. An oxide superconducting device (a Josephson Junction device) having a high degree of flexibility in arrangement and with high reproducibility, and having a high degree of uniformity is provided.
