Abstract
A process for preparing high-Tc superconducting integrated circuits by using a method in which a thin surface layer of non-superconducting tetragonal YBa.sub.2 Cu.sub.3 Oy wafer is selectively transformed into a superconducting orthorhombic phase by oxygen-diffusion. The superconducting orthorhombic islands are surrounded with non-superconducting tetragonal phases and these are electrically isolated from each other. The process results in the formation of superconducting integrated circuits which are inexpensive and are high in quality.
