Abstract
Various computer-implemented methods, carrier media, and systems for generating a metrology sampling plan are provided. One computer-implemented method for generating a metrology sampling plan includes identifying one or more individual defects that have one or more attributes that are abnormal from one or more attributes of a population of defects in which the individual defects are included. The population of defects is located in a predetermined pattern on a wafer. The method also includes generating the metrology sampling plan based on results of the identifying step such that one or more areas on the wafer in which the one or more identified individual defects are located are sampled during metrology.
