摘要
A process for preparing an YBCO oxide thin film which has a crystalline, clean and smooth surface on a substrate. The process is conducted by using an apparatus comprising a vacuum chamber in which an oxidizing gas of O.sub.2 including O.sub.3 can be supplied near the substrate so that pressure around the substrate can be increased while maintaining high vacuum near an evaporation source and K cell evaporation sources arranged in the vacuum chamber wherein the substrate is heated, molecular beam of constituent atoms of the oxide excluding oxygen are supplied from the K cell evaporation sources, and a chilled oxidizing gas is locally supplied to the vicinity of the substrate.
