Abstract

A superconductive junction device for fabricating Josephson integrated circuits is useful for replacing deposited thin-film resistors. Derived by 'poisoning' a superconductive electrode of the Josephson junction, the device displays controllable resistive properties at normal superconducting transition temperatures at substantial savings in the space occupied. Methods of fabricating the device using the selective niobium anodization process and conventional lead alloy processes are disclosed. When both upper and lower superconductive electrodes are poisoned, the device has linear properties whose resistance is identical to the normal resistance of unpoisoned junctions.
