Abstract: There is provided a film formation processing method for forming, in a vacuum atmosphere, a silicon nitride film along an inner wall surface of a recess constituting a pattern formed on a surface of a substrate, which includes: forming the silicon nitride film on the substrate by repeating, plural times, a process of supplying a raw material gas containing silicon to the substrate and subsequently, supplying an ammonia gas to the substrate to generate a silicon nitride on the substrate; and subsequently, modifying the silicon nitride film by activating a hydrogen gas and an ammonia gas and supplying the activated hydrogen gas and the activated ammonia gas to the substrate.

Abstract: A method for forming a silicon nitride film to cover a stepped portion formed by exposed surfaces of first and second base films in a substrate, includes: forming a nitride film or a seed layer to cover the stepped portion, wherein the nitride film is formed by supplying, to the substrate, a nitrogen-containing base-film nitriding gas for nitriding the base films, exposing the substrate to plasma and nitriding the surface of the stepped portion, and the seed layer is composed of a silicon-containing film formed by supplying a raw material gas of silicon to the substrate and is configured such that the silicon nitride film uniformly grows on the surfaces of the base films; and forming the silicon nitride film on the seed layer by supplying, to the substrate, a second raw material gas of silicon and a silicon-nitriding gas for nitriding silicon.

Abstract: A film forming process of forming a silicon nitride film by depositing a molecular layer of silicon nitride on a surface of a substrate, in which an uneven pattern is formed and a base made of metal reacting with halogen is exposed, includes alternately performing adsorbing silicon halide to the surface of the substrate and nitriding the silicon halide, wherein the film forming process is performed under a condition in which the substrate is heated at a film-forming temperature, the film-forming temperature falling within a range of equal to or higher than a minimum film-forming temperature at which the molecular layer of the silicon nitride is formed by reaction of the silicon halide and a plasmarized nitriding gas and less than a maximum film-forming temperature at which the reaction of the base made of metal and the silicon halide goes ahead.

Abstract: A method for processing a substrate is provided. According to the method, a process gas is supplied to a surface of a substrate, and then a separation gas is supplied to the surface of the substrate. Moreover, a first plasma processing gas is supplied to the surface of the substrate in a first state in which a distance between the first plasma generation unit and the turntable is set at a first distance, and a second plasma processing gas is supplied to the surface of the substrate in a second state in which a distance between the second plasma generation unit and the turntable is set at a second distance shorter than the first distance. Furthermore, the separation gas is supplied to the surface of the substrate.
