    摘要: A lithographic apparatus includes a device having a blade selectively insertable into the beam. The device is in a first plane intermediate a second plane conjugate to a plane of the substrate and a third plane conjugate to a pupil plane of the projection system. The blade may include a partially opaque blade and a solid blade or have a predetermined transmissibility pattern. The transmissibility may vary in a second direction perpendicular to the first direction in which the substrate and the patterning device are movable. In an illumination system including a field faceted mirror and a pupil faceted mirror, a reflecting blade is selectively insertable into the beam to reflect a portion of the beam to a beam dump that may be cooled to reduce a heat load. The reflecting element may have a coating that scatters the portion of radiation or changes the phase.

    摘要: A lithographic apparatus can include the following devices: a patterning system, a projection system, and a radiation beam inspection device. The patterning system can be configured to provide a patterned radiation beam. The projection system can be configured to project the patterned radiation beam onto a target portion of a substrate. Further, the radiation beam inspection device can be configured to inspect at least a part of the patterned radiation beam. In a substrate exposure position, the projection system is configured to expose a pattern of radiation on the substrate using the patterned radiation beam and the radiation beam device is configured to move the reflecting device away from a light path of the patterned radiation beam. In a radiation beam inspection position, the radiation beam inspection device is configured to move the reflecting device into the light path of the patterned radiation beam.

    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.
