Abstract:
1. 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; at least three substrate tables that are each constructed to hold a substrate; and a projection system configured to project the patterned radiation beam onto a target portion of the substrate, wherein the at least three substrate tables are moveable in a common moving area extending substantially in a plane substantially perpendicular to the patterned radiation beam, the moving area comprising at least three working locations of which at least one working location is arranged for exposure of the substrate to the patterned radiation beam and at least one working location is arranged for non-exposure purposes, and wherein the at least three substrate tables are moveable in said common area so that, in use, each of the at least three substrate tables is moveable to a position previously occupied by each of the remaining at least three substrate tables and each of the least three substrate tables is moveable to each of the at least three working locations.
