Abstract:
An immersion lithography apparatus has a controller configured to control a substrate table to move along an exposure route including in order: an entry motion in which the substrate moves from an off-substrate position at which the immersion space does not overlap the substrate to an on-substrate position at which the immersion space at least partially overlaps the substrate, a transfer motion in which the substrate table changes speed and/or direction and moves for at least a transfer time after the substrate moves to the on-substrate position, and an expose motion in which the substrate is scanned and the patterned beam is projected onto the substrate, wherein throughout the transfer motion at least a part of the immersion space overlaps the substrate and wherein the patterned beam is not projected onto the substrate during the entry motion and the transfer motion.

Claim (Index 22):
An immersion lithography apparatus comprising:\n a substrate table configured to support a substrate having a plurality of target portions; a projection system configured to project a patterned beam onto the substrate; a positioner configured to move the substrate table relative to the projection system;\n a liquid confinement structure configured to confine a liquid to an immersion space between the projection system and a surface of the substrate and/or the substrate table; and \n a controller configured to control the positioner to move the substrate table to follow an exposure route, the controller configured to at least:\n obtain routing instructions representing an order in which the target portions are to be exposed by projection of the patterned beam, \n predict locations on the substrate at which there is a risk of liquid being left behind if the target portions are exposed according to the routing instructions, \n generate modified routing instructions including an additional movement to reduce the risk of liquid being left behind during exposure of the target portions, and \n cause movement of the substrate table along an exposure route defined by the modified routing instructions.
