Abstract:
A film forming method, comprising the steps of:feeding a processing solution onto a surface of a substrate; rotating the substrate to disperse the processing solution, thereby forming a film of the processing solution which covers the entire surface of the substrate; removing the film of the processing solution formed at a peripheral edge portion of the substrate; solidifying the film of the processing solution formed at only a peripheral portion on an inside of the peripheral edge of the substrate, wherein the removing step and the solidifying step are carried out after the processing solution has covered the entire surface of the substrate; and wherein the removing step is carried out simultaneously with the solidifying step, by concurrently irradiating a first beam and a second beam to the film, the first beam being irradiated to a portion of the film to be removed, and the second beam being irradiated to a portion of the film to be solidified.
