摘要:
A resist coating method supplies a resist solution to substantially the center of a target substrate to be processed while rotating the target substrate at a first rotational speed, then decelerates the rotation of the substrate to a second rotational speed lower than the first rotational speed, or until rotational halt, makes the deceleration smaller in the deceleration step as the rotational speed becomes closer to the second rotational speed or the rotational halt, and accelerates the rotation of the substrate to a third rotational speed higher than the second rotational speed to spin off a residue of the resist solution.
