摘要
Decision trees and normalized reclassification are used to classify defects. Defect review sampling and normalization can be used for accurate Pareto ranking and defect source analysis. A defect review system, such as a broadband plasma tool and controller, may be used to bin defects using a decision tree based on defect properties and design properties. Class codes are assigned to at least some of the defects in each bean. Normalized reclassification assigns a class code to any unclassified defects in the bean. Additional decision trees can be used if any bean has more than one class code after normalized reclassification.
