Abstract: A thin film is formed from a solution including a component for forming the film and a solvent. By removing solvent molecules from the thin film until, effectively, none of the solvent molecules exist any longer in the atmosphere near the surface of the film while the atmosphere is at room temperature and a pressure 1 Pa or below, a thin film layer is formed from the solution including the film-forming component and the solvent. After the formation, vapor incursion from the solvent into subsequent processes is prevented.
