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 projection apparatus contains a projection system configured to project a patterned beam of radiation onto a target portion of a substrate. The projection system contains one or more optically active mirrors and heat shields located to intercept heat radiation to or from the mirrors and/or their support. The heat shields are actively cooled and the mirrors and the heat shields and the mirrors are supported separately on a support frame to reduce vibration of the mirrors due to active cooling. The heat shields may include heat shields that intercept heat radiation to or from the support and/or respective heat shields for individual mirrors that intercept heat radiation to or from the mirrors.

摘要： The present invention provides a lithographic apparatus comprising an illumination system for providing a projection beam of radiation. The illumination system comprises at least one movable optical element (7), such that a projection beam of radiation (4) can be shifted around a central position. This ensures that inhomogeneities in the intensity distribution in the projection beam (4) will be smeared out, which in turn provides an improved homogeneity of the exposure of a surface to be illuminated by the system, such as a wafer or other substrate. The optical element (7) may comprise a motor movable mirror, prism, filter, lens, axicon, diffuser, diffractive optical array, optical integrator, etc. The invention further provides a device manufacturing method, using a lithographic apparatus according to the invention, wherein the optical element is moved, in order to provide an optimum homogeneity for the projection beam of radiation.

摘要： A lithographic apparatus having a projection system that includes a plurality of mirrors arranged to project the patterned radiation beam onto a target portion of the substrate. The lithographic apparatus further includes an autofocus system having a light source, a position sensitive detector, and a light directing arrangement for directing a first portion of light from the light source to the position sensitive detector. The light directing arrangement further directs a second portion of light from the light source into the projection system and, after the second portion of light has traveled through the projection system to the substrate and back through the projection system to the light directing arrangement, the second portion of light is directed onto the position sensitive detector.
