Abstract:
1. A computer-implemented method for generating a defect sample for a wafer, comprising: identifying individual defects common to two or more of sets of defects, wherein each of the sets of defects is produced by a different one of multiple scans of a wafer; acquiring two or more sampling parameter sets, one for each of the multiple scans such that each of the two or more sampling parameter sets corresponds to one of the sets of defects, wherein the two or more sampling parameter sets are selected independent of each other by a user, and wherein each of the two or more sampling parameter sets comprises one or more defect attributes; selecting defects from each of the sets of defects based on the two or more sampling parameter sets, wherein said selecting comprises: creating a defect sample for the wafer comprising the defects selected from each of the sets of defects, wherein said identifying, said acquiring, said selecting, and said creating are performed by a computer system.
