Abstract

A method of measuring the quality of a simulated aerial image includes receiving as input a mask pattern for a chip design, simulating an aerial image of the mask pattern, calculating an error area representative of a deviation between an ideal boundary of the chip design and a boundary of the simulated aerial image, calculating maximum and average end-of-line deviations between the ideal boundary of the chip design and the boundary of the simulated aerial image, and displaying a worst quality area in the simulated aerial image as a function of the error area and the maximum and average end-of-line deviations for visual inspection.
