Abstract:
1. A lithographic apparatus, comprising: an illumination system configured to provide a beam of radiation; a support configured to support a patterning device, the patterning device configured to impart the beam with a pattern in its cross-section; a substrate table configured to hold a substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; a measurement system configured to generate an information signal including information about a position of either the patterning device, or the substrate, or the projection system, or a component of the projection system, or any combination thereof; and a control system configured to transform the information signal into at least a native feedback signal representing an imaging characteristic of the lithographic apparatus, said control system configured to generate a control signal on the basis of a native set-point signal and the native feedback signal, the control system controlling said position on the basis of the control signal.
