Abstract:
1. A developing method for developing a substrate, comprising the steps of: developing the substrate by supplying a developer to the substrate; rinsing the substrate by spinning the substrate while supplying a rinsing solution to the substrate; drying the substrate by spinning the substrate, including the step of starting supply of an inert gas from a nozzle directed substantially at right angles toward a point adjacent a spin center of the substrate in plan view, after finishing the rinsing step and while a film of the rinsing liquid is present on the substrate; and wherein, when the rinsing step ends, the drying step is started; wherein, in said drying step, the supplied inert gas breaks the film of the rinsing liquid, and said drying step continues supply of the inert gas until an end of a period allocated for said drying step; said rinsing step replaces the developer with the rinsing liquid; said developing step continues supply of the developer until an end of a period allocated for said developing step; and said rinsing step starts supply of the rinsing liquid immediately after the supply of the developer ends.
