Abstract:
1. A computer-implemented method for detecting defects on a wafer, comprising: acquiring raw output for a wafer generated by an inspection system; identifying one or more characteristics of the raw output that correspond to one or more geometrical characteristics of patterned features formed on the wafer; assigning individual output in the raw output to different segments based on the identified one or more characteristics of the raw output such that the one or more geometrical characteristics of the patterned features that correspond to each of the different segments are different, wherein the one or more geometrical characteristics that correspond to one of the different segments comprise one or more geometrical characteristics of page breaks, and wherein the one or more geometrical characteristics that correspond to another of the different segments comprise one or more geometrical characteristics of array areas; separately assigning one or more defect detection parameters to the different segments; and applying the assigned one or more defect detection parameters to the individual output assigned to the different segments to thereby detect defects on the wafer.
