发明名称 Defect classification utilizing data from a non-vibrating contact potential difference sensor
摘要 A method and system for identifying and classifying non-uniformities on the surface of a semiconductor or in a semiconductor. The method and system involves scanning the wafer surface with a non-vibrating contact potential difference sensor to detect the locations of non-uniformities, extracting features characteristic of the non-uniformities, and applying a set of rules to these features to classify the type of each non-uniformity.
