  • Microbridge superconducting device having support with stepped parallel surfaces
    Patent number: 4454522
    Abstract: An SNS microbridge superconductive device includes a substrate having first and second generally parallel surfaces which are separated by a generally perpendicular step. A first layer of superconductive material is formed on the first surface, and a second layer of superconductive material is formed on the second surface. A normal or non-superconductive material is formed over the two layers of superconductive material and the step. In fabricating the device, the step functions as a shadow mask during deposition of the superconductive material. The dimensions of the step can be accurately controlled, and the process utilizes conventional technology which is readily and uniformly reproducible.
