Disclosed is an improved Josephson Junction comprising a superconductor-separator-superconductor laminar deposition on a substrate, the overlying and underlying superconductor layers being laid offset to each other, and a weak link extending from one of the superconductor layers to the other across the thickness of the intervenient separator. A triple layer superconducting device according to this invention has as short barrier length and as low capacitance as possible, and is characteristic of a large product of junction resistance and critical current. Also, the geometrical configuration of the device is most appropriate for the purpose of massproduction.
