Abstract
It is an object to provide a method for forming a thin film which can be uniformly and precisely planarized without a high-loaded process as in a chemical mechanical polishing method and to provide a device used for the method. In a method for forming a thin film on a surface of a-semiconductor wafer as a substrate to be processed by supplying a coating solution to the wafer having asperities on the surface thereof, a thin film of a coating solution is planarized by placing the wafer having the thin film formed on the surface thereof in a solvent gas atmosphere generated in a treatment chamber, then spraying a solvent gas toward the surface of the wafer from a solvent-gas-supplying nozzle and, simultaneously, relatively moving the wafer and/or the solvent-gas-supplying nozzle in directions parallel to each other.
