Abstract
A method of producing a high temperature superconductor Josephson element for an electronic device or a photodetector comprising the steps of: forming a lower ceramic superconductor film on a substrate; forming an upper ceramic superconductor of a different system ceramic from that of the lower ceramic superconductor film on a portion of the lower ceramic superconductor and on the substrate; and forming an insulating layer (tunnel barrier) between the lower and upper ceramic superconductor films by an interdiffusion therebetween.
