Abstract
A lithographic apparatus having an illumination system configured to condition a radiation beam, a support constructed to support a patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; and, an actuator arranged to exert a force on an object, wherein the apparatus includes a thermal expansion error compensator configured to avoid an error caused by thermal expansion of the object by any heat dissipated by the actuator or another heat source.
