| description | PROBLEM TO BE SOLVED: To provide optimization of a light source suitable for image fidelity and throughput. SOLUTION: This method is used for optimizing a light source to generate a desired feature pattern on a wafer by photolithography processing. The method includes steps of: receiving at least a part of a layout database to select the desired feature pattern to be generated on a wafer; associating a plurality of pixel densities in the light source and contribution of pixels of the light source to one point on the wafer with the desired feature pattern by using a mathematical relationship; and determining the pixel density of the light source by using the mathematical relationship so that an error between a feature pattern generated on the wafer and the desired feature pattern is minimized at simultaneous irradiation of the pixels at a predetermined pixel density.
