Patent ID: 8330936

Claim:
A lithographic apparatus comprising: a support constructed to support a patterning device, the patterning device being capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table constructed to hold a substrate; a liquid supply system configured to provide liquid to a localized area of a top surface of a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate through the liquid; and a controller adapted to coordinate movement of the substrate table and the support during imaging of a line of dies across the substrate in a first direction such that movement of the substrate under the projection system in a plane substantially parallel to the top surface to image the line of dies is backwards and/or forwards only in a direction substantially parallel to the first direction which first direction is in the plane, wherein the controller is further adapted to, after the line of dies has been exposed, move the substrate in a second direction in the plane and substantially perpendicular to the first direction when the substrate is not under a space filled by liquid after an edge of the substrate passes across the localized area so that a localized surface of the substrate table replaces the substrate under the space and is in contact with said liquid and a last exposed die of said line of dies on said substrate is out of contact with said liquid, said space formed below and surrounded by a last optical element of the projection system, and then, during exposure of a second line of dies across the substrate, coordinate movement of the substrate table and the support such that movement of the substrate under the projection system in the plane to image the second line of dies is backwards and/or forwards only in a direction substantially parallel to the first direction.
