Coating treatment method, coating treatment apparatus, and computer-readable storage medium
Abstract:
In a coating step, a substrate is rotated at a high speed, and in that state a resist solution is discharged from a first nozzle to a central portion of the substrate to apply the resist solution over the substrate. Subsequently, in a flattening step, the rotation of the substrate is decelerated and the substrate is rotated at a low speed to flatten the resist solution on the substrate. In this event, the discharge of the resist solution by the first nozzle in the coating step is performed until a middle of the flattening step, and when the discharge of the resist solution is finished in the flattening step, the first nozzle is moved to move a discharge position of the resist solution from the central portion of the substrate. According to the present invention, the resist solution can be applied uniformly within the substrate.
