Abstract:
1. A systematic defect analyzing method, comprising: utilizing a processor to perform following steps: receiving a plurality of physical features and a plurality of equivalence classes of suspected physical sites of a portion or all of a chip; partitioning physical sites into groups to obtain a plurality of groups of physical sites according to the plurality of physical features of a chip corresponding to different potential systematic defects; computing at least one defect probability of each group of physical sites; and deriving an analysis result according to the plurality of defect probabilities corresponding to the plurality of groups of physical sites, wherein the analysis result includes a trend result; wherein the step of computing the defect probability of each of the groups of physical sites comprises: the step of deriving the analysis result according to the plurality of defect probabilities corresponding to the plurality of groups of physical sites comprises: obtaining the trend result according to the plurality of SCIs.
