Abstract:
A lithographic apparatus includes an illumination system configured to condition a radiation beam and 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. The lithographic apparatus further includes a substrate table constructed to hold a substrate; a positioner constructed to position the substrate table; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; a substrate surface actuator arranged to engage a part of a surface of the substrate facing the projection system, and a position controller configured to control a position of the substrate table, the position controller being arranged to drive the positioner and the substrate surface actuator.
