In a pattern measuring unit installed in a coating and developing treatment system, the height of a pattern formed on a substrate is measured using the Scatterometry method. Based on the measured height of the pattern, an appropriate number of rotations of the substrate during application of a coating solution is calculated, so that the rotation of the substrate during the application is controlled by the calculated number of rotations of the substrate. Since the number of rotations of the substrate when the coating solution is applied to the substrate is controlled, it is unnecessary to stop the system which performs photolithography processing on the substrate, resulting in improved productivity of the substrate.
