Claim 9:
10. A computer readable medium that is not transitory and stores instructions for
searching for a rare stochastic defect in a dense pattern of a substrate, wherein the rare stochastic defect appears in a functional pattern of the substrate with a defect density that is below 10−9 and appears in the dense pattern with a defect density that is above 10−7; wherein the dense pattern is a dense representation of the functional pattern that differs from the functional pattern by at least one out of (a) a distance between features of the dense pattern, and (b) a width of the features of the dense pattern; and
estimating an occurrence of the rare stochastic defect within the functional pattern based on an outcome of the searching.
