System, method and computer program product for systematic and stochastic characterization of pattern defects identified from a semiconductor wafer
First Claim
1. A non-transitory computer readable medium storing a computer program product having code executable by a processor to perform a method comprising:
- identifying a plurality of pattern defects detected from a fabricated component;
analyzing attributes of each of the pattern defects, based on predefined criteria;
determining, from the analysis, a first set of pattern defects of the plurality of pattern defects to be systematic pattern defects and a second set of pattern defects of the plurality of pattern defects to be stochastic pattern defects;
performing a first action for the determined systematic pattern defects; and
performing a second action for the determined stochastic pattern defects.

Abstract
A system, method, and computer program product are provided for systematic and stochastic characterization of pattern defects identified from a fabricated component. In use, a plurality of pattern defects detected from a fabricated component are identified. Additionally, attributes of each of the pattern defects are analyzed, based on predefined criteria. Further, a first set of pattern defects of the plurality of pattern defects are determined, from the analysis, to be systematic pattern defects, and a second set of pattern defects of the plurality of pattern defects are determined, from the analysis, to be stochastic pattern defects. Moreover, a first action is performed for the determined systematic pattern defects and a second action is performed for the determined stochastic pattern defects.
