Abstract:
A film forming method comprising the steps of:(a) holding a substrate to be processed, rotatably, with a spin chuck in a container;(b) starting to supply a mist-form solvent to a space above the substrate;(c) supplying a processing solution including a solvent onto an upper surface of the substrate, after step (b);(d) forming a closed processing space surrounding the substrate by closing a container, and rotating the substrate in the closed processing space while the closed processing space is filled with the mist-form solvent to disperse the processing solution by centrifugal force to form a film of the processing solution over the entire upper surface of the substrate; and(e) stopping the supply of the mist-form solvent to the closed processing space, and supplying air to the closed processing space to air-purge the closed processing space.
