Abstract:
A method of fabricating a Josephson device, comprising the steps of:forming a first superconducting layer on a substrate; forming an insulating film on said first superconducting layer; and forming a second superconducting layer on said insulating film, wherein said step of forming said second superconducting layer comprises the steps of: removing said insulating layer at least from a predetermined area so as to expose said first superconducting layer; conducting, after said step of removing said insulating layer, a first step of forming said second superconducting layer; and conducting a second step of forming said second superconducting layer directly on said second superconducting layer formed in said first step, wherein the first step is performed with a first set of conditions and the second step is performed with a second set of conditions, and wherein the first and second set of conditions are not identical.
