Claim 20:
21. A non-transitory computer-readable recording medium storing a program that causes, by a computer, a substrate processing apparatus to perform a process comprising:
performing a set a plurality of times, the set including:
(a) loading at least one substrate into a process container of the substrate processing apparatus;
(b) performing a process of forming a nitride film on the at least one substrate by supplying a film-forming gas to the at least one substrate supported by a support in the process container;
(c) unloading the processed at least one substrate from an interior of the process container; and
(d) supplying an oxidizing gas into the process container from which the processed at least one substrate has been unloaded so as to oxidize one part of the nitride film formed inside the process container in (b) into an oxide film and maintain another part of the nitride film, which is different from the one part of the nitride film, as it is without oxidizing the another part.
