ABSTRACT:
A method for forming a superconducting circuit is disclosed, comprising the steps of forming a mask pattern on a superconducting layer, forming a covering layer, containing a modifying element for superconductor, on the resultant structure, diffusing the modifying element for a superconductor, which is contained in the covering layer, into the superconducting layer to modify a corresponding location to a nonsuperconducting layer. A method for forming a multi-layer superconducting circuit is also disclosed, comprising sequentially repeating the same steps as set forth above over a substrate.
