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.
