Edge Chips – Macro Defects

Above is an example of a semiconductor wafer edge chip defect detected by EAGLEview. Note that a white circle around the semiconductor wafer indicates that an edge defect may have been detected. The semiconductor wafer edge ribbon will also indicate the wafer defect location based on 360 degrees with the flat or notch at 0 degrees. EAGLEview makes it easy to visualize and clearly see where the wafer defect resides.

On the far right side of the semiconductor wafer is an edge chip defect. Microtronic’s EAGLEview system’s measuring tool indicates that this semiconductor wafer edge chip defect is about 9mm long.
