Patent ID: 8851011

Claim:
A coating treatment apparatus for a substrate, comprising: a rotating and holding unit for holding the substrate and rotating the substrate at a predetermined speed; a nozzle for discharging a coating solution to the substrate at a predetermined timing; a nozzle moving mechanism for moving said nozzle in a radial direction of the substrate from a position above a central portion of the substrate; and a control unit programmed to control the rotating and holding unit, said nozzle, and said nozzle moving mechanism to execute a first step of discharging the coating solution from said nozzle to the central portion of the substrate with the substrate being rotated at a first speed by said rotating and holding unit to apply the coating solution over the substrate; a second step of decelerating, after the first step, the rotation of the substrate and rotating the substrate at a second speed which is lower than the first speed; and a third step of accelerating, after the second step, the rotation of the substrate to dry the coating solution on the substrate, wherein the discharge of the coating solution by said nozzle in the first step is continuously performed until a middle of the second step, and before the discharge of the coating solution is finished in the second step, said nozzle is moved to move a discharge position of the coating solution from the central portion of the substrate.
