摘要： A computer readable medium containing computer-executable instructions which cause a computer to execute processing steps that calculate a light intensity distribution formed on an image plane of a projection optical system. When executed, the medium causes a computer to execute the steps of dividing an effective light source into the plurality of areas, generating, for each of the plurality of areas, a plurality of shifted pupil functions by shifting a pupil function in accordance with a position of each of divided point sources, defining, for each of the plurality of areas, a matrix including the plurality of pupil functions, calculating, for each of the plurality of areas, eigenvalues and eigenfunctions by performing singular value decomposition of the matrix, and calculating, for each of the plurality of areas, the light intensity distribution based on a diffracted light distribution from the mask and the eigenvalues and the eigenfunctions.

摘要： A phase type computer hologram has a plurality of cells for applying a predetermined phase to different portions of a wavefront of light, wherein no phase skip larger than &pgr; is present in the cells. Such a phase type computer hologram can be produced by a process of determining phases for a plurality of cells, respectively, smoothening a distribution of the phases of the cells, by shifting the phase of at least one of the cells by 2&pgr;, and forming, on a substrate, the cells whose phase distribution is smoothened in the smoothening step.

摘要： A projection optical system having a multilayered film mirror arranged to provide an approximately uniform reflectance throughout a predetermined light incidence angle range to thereby assure a desired optical performance. A projection exposure apparatus having such a projection optical system, and a device manufacturing method using such an exposure apparatus. A non-periodic film is used in a reflection multilayered film upon a mirror having a largest light incidence angle range or a mirror having a largest average of light incidence angle, and this effectively reduces a pupil transmittance distribution in the projection optical system.
