Title: Josephson integrated circuit
Inventor: SAI CHIYOUSHIN
IPC: H01L27/18
Filed: 1985-06-13
Abstract: PURPOSE:To eliminate an effect by magnetic flux trapped by a grounding thin- film by forming lattice defects more than the grounding thin-film in a region, in which a Josephson circuit is fitted, to at least one part of the grounding thin-film in a region in which the Josephson circuit is not mounted. CONSTITUTION:Currents are made to flow into a grounding thin-film 1 by using vortex driving-current supply terminals 10, and magnetic flux (vortexes) trapped in the grounding thin-film 1 by Lorentz's force generated at that time is driven. A Josephson integrated circuit is initiated concentrated partially to regions 11 in the periphery of a grounding surface in which a larger number of lattice defects having strong pinning force are formed. Accordingly, the effect of magnetic flux trapped by the grounding thin-film can be avoided while a peripheral external magnetic field is made small when a Josephson circuit thin-film is transferred to a superconducting state, thus preventing the generation of the trapping of magnetic flux.

If the elements are two terminal elements, rectifying current flows in a variable resistor 5, DC ammeter 6 and conductor 7, whereby the electro aging of the elements may be performed. The method is efficient because even if short-circuit elements are included, there is no need for removing these. The electrodes 11 are so installed that their axial direction is nearly parallel with the field direction of the radiation electromagnetic waves. In this case, the transverse plates 13 of the lead frame make the action analogous to a voltage equalizing ring.
