Wafer Contamination – Small

Contamination Small - Semiconductor Wafer Macro Defect Image -1

EAGLEview detects small contamination defects on the semiconductor wafer instantly. Typically, any small semiconductor wafer defect that is not a scratch or particle might be considered a small contamination macro defect. The image above shows a small contamination semiconductor wafer macro defect magnified 4x.
