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.
