DEFECT SENSITIVITY OF SEMICONDUCTOR WAFER INSPECTORS USING DESIGN DATA WITH WAFER IMAGE DATA

摘要

Criticality of a detected defect can be determined based on context codes. The context codes can be generated for a region, each of which may be part of a die. Noise levels can be used to group context codes. The context codes can be used to automatically classify a range of design contexts present on a die without needing certain information a priori.
