Abstract:
A method of forming a high-T.sub.c superconducting junction, the method comprising the steps of:a) depositing a first high-T.sub.c superconductive layer on a surface of a substrate, the first high-T.sub.c superconductive layer having a first thickness;b) depositing a dielectric layer on the first high-T.sub.c superconductive layer;c) forming a ramp edge on the first high-T.sub.c superconductive layer and the dielectric layer, the ramp edge being inclined relative to the surface of the substrate;d) depositing a second high-T.sub.c superconductive layer on the ramp edge, the second high-T.sub.c superconductive layer having a second thickness less than the first thickness;e) depositing a conductive barrier layer on the second high-T.sub.c superconductive layer, the barrier layer being comprised of a normal material that is non-superconductive at the operating temperature of the superconducting junction; andf) depositing a third high-T.sub.c superconductive layer on the barrier layer.
