ABSTRACT:
Superconductive integrated logic gate circuits of the magnetically controlled type incorporating Josephson tunnel junctions utilize a superconductive layer that forms a base electrode for Josephson junction devices on the integrated circuit, a ground plane, and magnetic control lines. A layer of super-conductive material superposed on a barrier layer provides inductive loops connected to junction counterelectrodes and coupled to the magnetic control lines. By patterning the control lines in the same plane as the ground plane-base electrode layer, two layers, an insulating layer and a super-conductive layer, can be eliminated from the prior art structure of a 1:2:1 magnetically controlled logic gate interferometer. A preferred embodiment utilizing an all refractory superconductor-barrier-superconductor trilayer patterned by local anodization is also described. Processes for manufacturing the embodiments of the invention are disclosed.
