Abstract

PURPOSE:To obtain an integrated circuit with Josephson effect element having a plenty of mass productivity by employing a superconducting material only at least in a microbridge in the Josephson effect element. CONSTITUTION:In a Josephson effect element, electrode wirings made of normal conductive material, such as IH or the like are formed through a microbridge 3 formed on an insulating film 4 on an insulating substrate 1, and a superconducting film 5 mad of YBaCu oxide is formed on the microbridge 3. Here, a superconducting material can be employed only as the microbridge even in a structure in which a step is formed in the microbridge on the substrate 1 or a microbridge structure having a neck wiring structure. Further, it can be also applied to a type employing a superconductor only as both electrodes disposed at both sides of a point contact or tunnel insulating film of a Josephson effect element having the point contact or the tunnel insulating film.
