Patent ID: 7016016

Claim:
A lithographic apparatus, comprising: an illumination system that supplies a projection beam of radiation; an array of individually controllable elements that patterns the projection beam; a projection system that projects the patterned beam onto a target portion of a substrate on a substrate table; and a substrate displacement control system that (1) displaces the substrate relative to the substrate table and the projection system in a predetermined direction, such that the patterned beam is scanned across the substrate and (2) determines the position of the substrate relative to the substrate table and the projection beam, the displacement control system comprising: at least one component that is displaceable with the substrate, and a positioning apparatus to place the at least one component in contact with the substrate, such that (1) the at least one component is displaced with the substrate as the patterned beam is scanned across the substrate and (2) the at least one component is removed from the substrate after the patterned beam has been scanned across the substrate.
