    摘要: A system and method of matching multiple scanners using design and defect data are described. A golden wafer is processed using a golden tool. A second wafer is processed using a second tool. Both tools provide focus/exposure modulation. Wafer-level spatial signatures of critical structures for both wafers can be compared to evaluate the behavior of the scanners. Critical structures can be identified by binning defects on the golden wafer having similar patterns. In one embodiment, the signatures must match within a certain percentage or the second tool is characterized as a “no match”. Reticles can be compared in a similar manner, wherein the golden and second wafers are processed using a golden reticle and a second reticle, respectively.
