Abstract:
1. A coating and developing apparatus having a resist film forming unit that applies a resist solution to a front surface of a substrate to form a resist film, and a developing unit that develops the resist film having been subjected to immersion exposure, the coating and developing apparatus comprising: a first peripheral edge cleaner that supplies a solvent to the resist film present in a peripheral edge portion of the substrate thereby to remove the same; a protective film forming unit that supplies a coating solution onto the resist film thereby to form a water-repellent protective film that protects the resist film from a liquid when performing the immersion exposure; an adhesion-improving processor having an adhesion-improving fluid feeder that supplies, before forming the protective film, an adhesion-improving fluid only to the peripheral edge portion of the substrate, the peripheral edge portion having an exposed surface exposed due to removal of the resist film from the peripheral edge portion, wherein the adhesion improving fluid improves adhesion of the protective film to the exposed surface, wherein: the adhesion-improving processor further has a rotary stage configured to rotate about a vertical axis while holding the substrate horizontally; and the adhesion-improving fluid feeder has: the adhesion improving processor is installed within the protective film forming unit, and the rotary stage in the protective film forming unit is used as the rotary stage in the adhesion-improving processor.
