Abstract: Described herein is a method for source mask optimization with a lithographic projection apparatus. The lithographic projection apparatus comprises an illumination source and projection optics configured to image a mask design layout onto a substrate. The method comprises determining a multi-variable source mask optimization function using a plurality of tunable design variables for the illumination source, the projection optics, and the mask design layout. The multi-variable source mask optimization function accounts for imaging variation across different positions in an exposure slit corresponding to different stripes of the mask design layout exposed by the same slit position of the exposure apparatus. The method comprises iteratively adjusting the plurality of tunable design variables in the multi-variable source mask optimization function until a termination condition is satisfied.

Abstract: A lithographic system is provided in which an extent of overlap between pattern sections is adjusted in order to match a size of a pattern section to a size of a repeating portion of the pattern to be formed.
