ABSTRACT:
A Josephson junction element which comprises a substrate, a first strip-like superconductor thin film layer arranged on said substrate, a second strip-like superconductor thin film layer arranged on said first superconductor layer in crossing relation thereto, an insulator layer disposed between said first and second superconductor layer at the crossing area and a weak link portion connecting said first and second layer together across the sides of the thickness of said insulator layer. A method for manufacturing such Josephson junction element.
