    摘要: A method of controlling a spectral property of a light beam includes directing a light beam to a lithography exposure apparatus configured to create a pattern on a wafer; receiving information representative of a spectral property of the light beam; receiving information representative of an optical imaging condition of the lithography exposure apparatus; estimating a characteristic value of the light beam based on the received spectral property information and the received optical imaging condition information; determining whether the estimated light beam characteristic value matches a target light beam characteristic value; and if it is determined that the estimated light beam characteristic value does not match the target light beam characteristic value, adjusting the spectral property of the light beam.

    摘要: A method for determining an image of a patterned object formed by a polychromatic lithographic projection system having a laser radiation source of a finite spectral bandwidth and a lens for imaging the patterned object to an image plane within a resist layer. The method comprises providing patterns for the object, a spectrum of the radiation source to be used in the lithographic projection system, an intensity and polarization distribution of the radiation source, and a lens impulse response in the spatial domain or in the spatial frequency domain of the image. The method then includes forming a polychromatic 4D bilinear vector kernel comprising a partially coherent polychromatic joint response between pairs of points in the spatial domain or in the spatial frequency domain, determining the dominant polychromatic 2D kernels of the polychromatic 4D bilinear vector kernel, and determining the image of the patterned object from convolutions of the object patterns with the dominant polychromatic 2D kernels.
