Abstract
An improvement in a process for manufacturing a superconductor, characterized by irradiating a material composed of compound oxide by one of ion beams selected from oxygen ion beam, inert gas ion beams and an ion beam consisting of a mixture of oxygen gas and inert gas to convert said material into a superconductor. When a focused ion beam is directed onto desired areas on said film layer, the areas irradiated by the ion beam are converted to a superconductor in a form of a superconducting circuit.
