Superconducting device and method of manufacturing the same

摘要

The present invention provides a superconducting device including a substrate (1), a first superconducting pattern (3a) formed on the substrate, an insulating pattern (5a) formed on the first superconducting pattern, and a second superconducting pattern (8a) formed at the uppermost level in the multilayered superconducting pattern. A barrier layer of a Josephson junction is formed on the lower side of, or within the second superconducting pattern. The second superconducting pattern constitutes a circuit element on the insulating pattern.
