发明名称 DEVELOPING APPARATUS, DEVELOPING METHOD AND STORAGE MEDIUM
摘要 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.
