    摘要: Systems and methods are provided for measuring aberration in a lithographic apparatus. A radiation beam is modulated using an array of individually controllable elements, and the modulated beam is projected using a projection system. A pattern is provided on the array of individually controllable elements to modulate the radiation beam, and the pattern comprises a repeating structure that is formed from a plurality of features that are dimensioned such that first order diffraction of the radiation beam substantially fills the pupil of the projection system. A sensor detects the projected radiation and measures interference in the radiation projected by the projection system. Aberration in the detected radiation beam is then measured.

    摘要: A lithographic apparatus, a device manufacturing method, and a projection element for use in a lithographic apparatus are disclosed. The lithographic apparatus has a radiation system for providing a pulsed beam of radiation, a patterning device for imparting the beam with a pattern to form a patterned radiation beam, and a projection system having a projection element for projecting the patterned beam onto a target portion of a substrate. The apparatus further comprises an actuator for moving the projection element for shifting the patterned beam that is projected onto the substrate during at least one pulse of the radiation system. This can be done to compensate for a positional error between a substrate table holding the substrate and an aerial image of the projection system. The positional error could occur due to mechanical vibrations in the frame system of the lithographic apparatus.
