Claim Text:
1. A method for classifying defects detected on a wafer, comprising: creating a decision tree for classification of defects detected on a wafer, wherein the created decision tree comprises a plurality of floating trees; altering two or more floating trees in the plurality of floating trees in the created decision tree, wherein the two or more floating trees are manipulated as individual units, and wherein altering the two more floating trees comprises arranging the two or more floating trees in parallel with each other where at least one of the defects is passed through the two or more floating trees in parallel; and classifying the defects detected on the wafer by applying the altered and created decision tree to the defects, wherein classifying the defects comprises determining if each of the defects is binned into more than one class and when a defect is binned into more than one class, arbitrating among classes the defect is binned into to determine a final classification for the defect, wherein said creating and said classifying are performed by one or more computer systems, and wherein the one or more computer systems comprise one or more devices having one or more processors that execute instructions from a memory medium.
