Abstract:
1. A resist applying and developing method comprising: forming a resist film on a substrate; exposing the resist film formed on the substrate to a light generated by an ArF excimer laser using a reticle; developing the exposed resist film, thereby patterning the resist film on the substrate; decomposing an adamantly group and/or a lactone group serving as a protection group in the resist film by irradiating an ultraviolet light on the resist film patterned by the developing; heating the resist film, during or after the irradiation of the ultraviolet light, thereby facilitating decomposition of the adamantly group and/or the lactone group; and introducing a benzene ring to the protection group in the resist film by exposing the resist film to a solvent gas that contains the benzene ring, during or after the heating of the resist film.
