    摘要: A method for configuring an illumination source of a lithographic apparatus, the method including dividing the illumination source into pixel groups, each pixel group including one or more illumination source points in a pupil plane of the illumination source; changing a polarization state of each pixel group and determining an incremental effect on each of the plurality of critical dimensions resulting from the change of polarization state; calculating a first plurality of sensitivity coefficients for each of the plurality of critical dimensions using the determined incremental effects; selecting an initial illumination source; iteratively calculating a lithographic metric as a result of a change of polarization state using the calculated first plurality of sensitivity coefficients, the change of the polarization state of the pixel group in the initial illumination source creating a modified illumination source; and adjusting the initial illumination source based on the iterative results of calculations.

    摘要: A apparatus having a projection system to project a plurality of radiation beams onto a substrate, wherein the plurality of radiation beams includes a first group of one or more radiation beams formed from radiation within a first wavelength range and a second group of one or more radiation beams formed from radiation within a second wavelength range, different from the first wavelength range. The apparatus also has a dispersion element configured such that one or more radiation beams of the first group are incident on the dispersion element at a different angle from the one or more radiation beams of the second group and such that the one or more radiation beams of the first and second group output from the dispersion element are substantially parallel.
