  • Patent number: 9976217
    Abstract: The method of forming a thin film feeds a raw material gas causing a reversible decomposition reaction toward an upper surface of substrate placed on a placing table in a processing container; decomposes the raw material gas with a predetermined decomposing scheme thereby forming a thin film of the raw material gas on the surface of the substrate; and feeds a decomposition restraint gas having a characteristic of restraining a thermal decomposition of the raw material gas separately from the raw material gas toward a peripheral portion of the substrate when the raw material gas is fed to the substrate, thereby restraining the thermal decomposition of the raw material gas and selectively preventing the thin film from being formed in the peripheral portion of the substrate.
