Abstract
In a method of manufacturing a device comprising a film of an oxide superconducting material which comprises an alkaline earth metal, another metal component, copper and oxygen. A superconductor precursor material comprising copper oxide, alkaline earth metal fluoride and another metal or metal oxide, is provided on a substrate in the form of a film. The film is covered with a diffusion barrier against water in accordance with a pattern which is complementary to a desired pattern of superconducting material. Subsequently, the superconducting material is formed in the uncovered portions of the pattern by means of a treatment at an increased temperature in the presence of water and oxygen.
