Abstract:
A method of forming a coating film on a substrate, comprising:holding the substrate by a substrate holder in a process space, the substrate holder holding the substrate to direct upward a surface to be provided with the coating film; supplying a coating solution for forming the coating film onto the surface of the substrate from a nozzle unit while moving the substrate holder and the nozzle unit relative to each other, the coating solution being continuously discharged as a stream from a discharge hole of the nozzle unit; and maintaining a solvent atmosphere of a predetermined concentration in the process space by an atmosphere control mechanism, the atmosphere control mechanism being configured to control a temperature and a surface level of a solvent and including a solvent channel positioned to store the solvent, a top plate member defining a ceiling of the process space and having an insertion section in which the nozzle unit is inserted, and a heater disposed on the top plate member to heat the process space and the nozzle unit.
