Abstract:
A developing apparatus for heaping a developing solution to a front face of a substrate to perform developing in an atmosphere in which an air stream toward the front face of the substrate is formed, comprising:a substrate holding section for holding the substrate;a supply section for supplying the developing solution to the substrate;a first current plate provided on the front face side of the substrate held by the substrate holding section to oppose the substrate and in which first air holes are formed;a second current plate provided to oppose the first current plate to move in a plane direction relative to the first current plate and in which second air holes are formed; andairflow amount adjustment means for moving the first current plate and the second current plate relative to each other in the plane direction to overlap the first air holes and an area of the second current plate where the second air holes are not formed in a direction orthogonal to the plane direction to thereby adjust sizes of the first air holes and control an airflow amount of an air current blowing against the front face of the substrate.
