Abstract

A method of forming a thin film wherein a gas which contains an element used to constitute a desired thin film as at least a part of its constituent elements or a condensed solid layer of this gas is irradiated with a high output power laser beam to dissociate the gas or the solid layer of the gas and thereby locally produce a plasma, and a substrate is irradiated with reactive particles produced in the plasma, thereby obtaining a highly-pure high-quality thin film. Also disclosed is an apparatus for realizing this method.
