Abstract:
1. A developing method for developing a substrate, comprising: spinning the substrate with a spin holder; discharging a developer to the substrate from a plurality of exhaust ports arranged in a row on a developer feeder; causing a moving mechanism to move said developer feeder in one direction extending to a center of the substrate in plan view while maintaining a direction of arrangement of said exhaust ports in said one direction, thereby to move said developer feeder between substantially the center and an edge of the substrate in plan view; and causing the developer discharged from said exhaust ports to impinge in separate streams on the substrate at loci of positions of impingement, and causing each of the separate streams to impinge spirally on the substrate, thereby to develop the substrate, wherein the developer discharged from said exhaust ports flows down in bar-shaped streams; wherein the loci of positions of impingement of the developer corresponding to said exhaust ports overlap each other.
