Claim 7:
8. The method according to claim 1, comprising:
searching for another rare stochastic defect in another dense pattern of the substrate; wherein the other rare stochastic defect appears in another functional pattern of the substrate with a defect density that is below 10−9 and appears in the other dense pattern with a defect density that is above 10−7; wherein the other dense pattern is a dense representation of the other functional pattern that differs from the other functional pattern by at least one out of (a) a distance between features of the other dense pattern, and (b) a width of the features of the other dense pattern; wherein the other rare stochastic defect differ from rare stochastic defect by type; and
estimating the occurrence of the other rare stochastic defect within the other functional pattern based on an outcome of the searching for the other rare stochastic defect.
