Abstract
A superconductive electrical device is operable simultaneously at relatively higher temperatures, i.e., 60-90K, and at relatively lower temperatures, i.e., less than 12K. The device comprises a non-superconductive substrate with two regions, a first relatively high temperature region and a second relatively low temperature region. A high temperature superconductor is on the first region and a portion of the second region. A dielectric layer is on the high temperature superconductor. A low temperature superconductor is on the second region of the substrate and on a portion of the dielectric layer. Integrated circuit chips can be secured to both superconductors, thereby yielding a superconductive multi-chip module operable at two different temperatures, such as in a cryo-cooler with two temperature stages.
