Abstract:
An exposure apparatus exposes a substrate with an exposure beam via a projection system supported by a frame. A substrate stage having a table that mounts the substrate is placed on a base under the projection system. A measurement device has a plurality of heads provided at the table and each irradiate a measurement beam on a grating section supported by the frame, and measures positional information of the table by a head of the plural heads, that faces the grating section. A drive device drives the substrate stage to move the substrate. A controller controls a drive of the substrate stage based on displacement information of a head used in measurement of the positional information or correction information to compensate a measurement error of the measurement device that occurs due to a displacement of the head, and based on the positional information measured by the measurement device.
