Abstract
There is disclosed a superconductor junction structure comprising: a first superconducting layer of an oxide superconductor formed in a desired pattern on a substrate; a non-superconducting layer of a non-superconductor formed on at least a part of the side faces of the first superconducting layer, a portion of the surface of the substrate near the part, and a top face of the first superconducting layer; and a second superconducting layer of the oxide superconductor formed on the non-superconducting layer, the non-superconducting layer being formed thin at the part, and forming a tunnel barrier. And further there is disclosed a process for fabricating a superconductor junction structure comprising: the first step of forming a first superconducting layer of an oxide superconductor in a desired pattern on a substrate; the second step of forming a non-superconducting layer of a non-superconductor formed on at least a part of the side faces of the first superconducting layer, a portion of the surface of the substrate near the part, and a top face of the first superconducting layer by depositing the non-superconductor from the above; and the third step of forming a second superconducting layer of the oxide superconductor on the non-superconducting layer.
