Abstract

A process for fabricating a superconducting oxide thin film is disclosed which comprises the steps of separately evaporating metal elements, of which the superconducting oxide thin film with a desired stoichiometry is to be composed, to a substrate and simultaneously irradiating the substrate with oxygen plasma generated by RF wave or ECR microwave to form a crystalline oxide film without further annealing.
