Abstract:
A method for improving a lithographic process for imaging a portion of a design layout onto a substrate using a lithographic projection apparatus, the method including: calculating a discrete pupil profile based on a desired pupil profile; selecting a discrete change to the discrete pupil profile; and applying the selected discrete change to the discrete pupil profile. The methods according to various embodiments disclosed herein may reduce the computational cost of discrete optimization from O(a n ) to O(n) wherein a is constant and n is the number of knobs that can generate discrete change in the pupil profile.

Claim (Index 35):
The computer program product of  claim 33 , wherein the instructions are further configured to cause the computer system to calculate a plurality of gradients of a cost function, each of the plurality of gradients being with respect to intensity at one of a plurality of spatially discrete positions on a pupil plane.
