Patent ID: 7675201

Claim:
A lithographic apparatus comprising: a patterning device support constructed to hold 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 support constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; an additional support; a flexible line assembly configured to transfer at least one of a current, a signal or a fluid, the line assembly having a first part extending between a base and the additional support, and having a second part extending between the additional support and one of either the patterning support or the substrate support; a first motor assembly configured to generate a force in at least one direction, the first motor assembly being coupled to said one of either the patterning support or the substrate support; a second motor assembly configured to generate a force in said at least one direction, the second motor assembly being coupled to the additional support; an actuator separate from the first and the second motor assembly, said actuator configured to provide an actuation force between a first side of the additional support and a second side of said one of either the patterning support or the substrate support, said first side extending at least partially along, and spaced apart from, said second side, wherein the first motor assembly comprises a planar motor, and wherein, in use, the first motor assembly and the second motor assembly are configured to move said one of either the patterning support or the substrate support and the additional support, respectively, over a same surface with said one of either the patterning support or the substrate support and said additional support spaced apart from each other.
