Abstract:
A liquid film formation apparatus comprising:a substrate holding portion for holding a substrate substantially horizontally so as to allow a pattern-to-be-formed surface to face upward;a liquid-receiving base surrounding the substrate held by the substrate holding portion and having a liquid-receiving face which is placed at substantially the same level as that of an upper surface of the substrate;a supply nozzle having a process-liquid spray section whose length is equal to or longer than the width of an effective region of the substrate; anda moving mechanism for moving said supply nozzle in the direction perpendicular to the longitudinal direction of the supply nozzle;whereinsaid substrate holding portion seals a slit formed between the liquid-receiving base and the outer peripheral portion of the substrate so as not to leak out the process solution from the slit, andthe process solution is supplied from said supply nozzle to said liquid-receiving base to mount the process solution on the liquid-receiving base, andthe process solution is subsequently mounted over an entire surface of the substrate by spraying the process solution from the supply nozzle while moving the supply nozzle.
