ABSTRACT:
The present invention is an tri-phase epitaxy method for preparing a single crystal oxide thin film, comprising the steps of depositing on a substrate an oxide thin film serving as a seed layer and having the same composition as that of an oxide thin film to be formed, depositing on the seed layer a thin film comprising a substance capable of being melted and liquidized by heat from the substrate and dissolving the oxide to be subsequent by deposited onto the seed layer, heating the substrate to form a liquid layer, and depositing an oxide on the seed layer through the liquid layer by use of a vapor-phase epitaxy method to form the single crystal oxide thin film. In this method, the oxygen partial pressure on the liquid layer is set in the range of 1.0 to 760 Torr during the film-forming step.
