Abstract
A method for aligning a measured image of a pattern printed on a substrate with a design layout. The method includes: obtaining a design layout of a pattern to be printed on a substrate and a measured image of the pattern printed on the substrate; performing a simulation process to generate a plurality of simulated contours of the design layout for a plurality of process conditions of a patterning process; identifying a set of disfavored locations based on the simulated contours; and performing an image alignment process to align the measured image with a selected contour of the simulated contours using locations other than the set of disfavored locations.
