Abstract
Disclosed is a film-forming method, comprising dispensing from a dispenser nozzle a coating solution, which is prepared by adding a solid component to a solvent and controlled to be spread on the substrate in a predetermined range, onto a target substrate to be processed while relatively moving the dispenser nozzle and the target substrate so as to form a liquid film on the entire surface of the target substrate, and arranging a sucking nozzle above and apart from the target substrate such that the sucking nozzle is not in contact with the surface of the liquid film so as to permit the sucking nozzle to suck the solvent vapor right under the sucking nozzle while moving the sucking nozzle relative to the target substrate, thereby removing the solvent from the liquid film and, thus, forming a coated film.
