    摘要: Calibration of an angularly resolved scatterometer is performed by measuring a target in two or more different arrangements. The different arrangements cause radiation being measured in an outgoing direction to be different combinations of radiation illuminating the target from ingoing directions. A reference mirror measurement may also be performed. The measurements and modeling of the difference between the first and second arrangements is used to estimate separately properties of the ingoing and outgoing optical systems. The modeling may account for symmetry of the respective periodic target. The modeling typically accounts for polarizing effects of the ingoing optical elements, the outgoing optical elements and the respective periodic target. The polarizing effects may be described in the modeling by Jones calculus or Mueller calculus. The modeling may include a parameterization in terms of basis functions such as Zernike polynomials.

    摘要: A wafer or substrate alignment system for a lithographic apparatus, capable of exhibiting reduced tilt sensitivity, is presented herein. In particular, the substrate alignment system detects a position of a substrate relative to a position of a patterning device and includes a source configured to generate an incoming optical beam, at least one grating, provided on the substrate, having a diffracting length, in which the at least one grating is configured to generate at least one diffraction order of constituent diffracted beams based on an interaction with the incoming optical beam over the diffracting length. The system further includes an optical device, configured to image the at least one diffracted order on a sensor device, and includes aperture at a predetermined location to allow the constituent diffracted beams to pass through. The optical device is arranged to broaden the constituent diffracted beams such that a beam diameter of the constituent diffracted beams is larger than a diameter of the aperture, in order to reduce the sensitivity to tilt.
