Claim:
1. A method of manufacturing a semiconductor device, comprising: carrying a substrate into a process container; forming a thin film on the substrate by supplying a source gas into the process container accommodating the substrate, the source gas containing a certain element and a halogen element; performing a first modification treatment to an adsorption layer of a residual source gas adhered to inside of the process container by simultaneously supplying a combination of gases consisting of oxygen (O carrying the thin film-formed substrate out of the process container; and performing a second modification treatment to the modified adsorption layer adhered to the inside of the process container, which is formed by performing the first modification treatment to the adsorption layer of the residual source gas and being oxidized by a water in an atmosphere penetrated into the process container in the carrying of the thin film-formed substrate out of the process container, the second modification treatment consisting of simultaneously supplying a combination of gases consisting of oxygen (O wherein the simultaneous supply of the combination of gases consisting of the oxygen (O
