Example of semiconductor wafer macro defect that is a scratch made by a person as opposed to a machine. Scratches made by operators usually look like a shaky line typically due to wafer handling. Macro defect scratches made by machines usually look very straight in comparison.
Additional example of a semiconductor wafer scratch made by a person. EAGLEview easily identifies scratches no matter where they occur on the semiconductor wafer.
