Abstract
An apparatus includes: an capturing part that captures a peripheral edge portion of a substrate including a reference substrate and a workpiece substrate, so as to acquire captured images of the reference and workpiece substrates; a first calculation part that calculates a theoretical peripheral edge position of the reference substrate in the captured image of the reference substrate with reference to a center thereof; a second calculation part that calculates a theoretical peripheral edge position of the workpiece substrate in the captured image of the workpiece substrate based on the theoretical peripheral edge position of the reference substrate and the captured image of the workpiece substrate; a setting part that sets processing parameters for the peripheral edge portion of the substrate based on the theoretical peripheral edge position of the workpiece substrate; and a processing part that processes the peripheral edge portion of the substrate based on the processing parameters.
