    摘要: In a method according to one embodiment of the invention, aberrations in a lithographic apparatus are detected by printing a test pattern having at least one degree of symmetry and being sensitive to a particular aberration in the apparatus, and using a scatterometer to derive information concerning the aberration. The test structure may comprise a two-bar grating, in which case the inner and outer duty ratios can be reconstructed to derive information indicative of comatic aberration. Alternatively, a hexagonal array of dots can be used, such that scatterometry data can be used to reconstruct dot diameters indicative of 3-wave aberration.

    摘要: A lithographic apparatus includes an illumination system configured to provide a beam of radiation and projection system configured to project the radiation beam onto a target portion of a substrate. At least one of the illumination system and the projection system includes a focusing element for reflecting or refracting the beam. A plurality of stop discs is provided, each having an aperture therethrough, together with a disc positioner configured to place one of the stop discs adjacent the focusing element to control the numerical aperture (NA) of the projection system or illumination system. The apparatus further includes a disc changer configured to select one of the stop discs and provide the selected stop disc to the disc positioner, the disc changer being external to the projection system or illumination system.
