    摘要: A lithographic apparatus includes an illumination system constructed and arranged to condition a radiation beam, and a support constructed and arranged to support a patterning device. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The apparatus also includes a substrate table constructed and arranged to hold a substrate, and a projection system constructed and arranged to project the patterned radiation beam onto a target portion of the substrate. The substrate table includes a chuck having a plurality of protrusions constructed and arranged to support corresponding parts of a bottom surface of a wafer. The top surface of at least one of the protrusions includes a plurality of elements that define a reduced contact area between the substrate and the top surface of the protrusion.

    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.
