Abstract: A developing apparatus includes: a substrate holder that hold a substrate horizontally; a developer nozzle that supplies a developer onto the substrate to form a liquid puddle; a turning flow generation mechanism including a rotary member that rotates about an axis perpendicular to the substrate while the rotary member is being in contact with the liquid puddle thereby to generate a turning flow in the liquid puddle of the developer formed on the substrate; and a moving mechanism for moving the turning flow generation mechanism along a surface of the substrate. The line-width uniformity of a pattern can be improved by forming turning flows in a desired region of the substrate and stirring the developer.

Abstract: A developing method including a developing step in which, while a wafer horizontally held by a spin chuck is being rotated, the wafer is developed by supplying a developer onto a surface of the wafer, wherein provided before the developing step is a pre-wetting step in which, simultaneously with the developer being supplied from a first nozzle that is located on a position near a central part of the surface of the rotating wafer, a deionized water as a second liquid is supplied from a second nozzle that is located on a position nearer to an outer peripheral part of the wafer than the first nozzle, to thereby spread out the developer in the rotating direction of the wafer by a wall that is formed by the deionized water flowing to the outer peripheral side of the wafer with the rotation of the wafer.
