Claim:
1. A method of forming a thin film, comprising: performing a first film formation process of, while an interior of a reaction chamber accommodating an object to be processed is heated to a predetermined temperature, alternately supplying a plurality of times: an organic metal compound gas into the reaction chamber to adsorb the organic metal compound onto the object to be processed, and H2O as the only oxidizing agent into the reaction chamber heated to the predetermined temperature to oxidize the organic metal compound adsorbed onto the object to be processed, thereby forming a thin film; after the first film formation process is ended, performing once an annealing process of, while the interior of the reaction chamber is heated to the predetermined temperature, supplying ozone having stronger oxidizing power than H2O into the reaction chamber; and after the annealing process is ended, performing a second film formation process of, while the interior of the reaction chamber is heated to the predetermined temperature, alternately supplying a plurality of times: the organic metal compound gas into the reaction chamber to adsorb the organic metal compound onto the thin film formed in the first film formation process, and ozone as the only oxidizing agent into the reaction chamber heated to the predetermined temperature to oxidize the organic metal compound adsorbed onto the thin film formed in the first film formation process, thereby forming a thin film.
