The spacing between the chatter marks
will indicate whether it is the contact roller or a defective abrasive belt.

Designed for semiconductor manufacturers running advanced metals processes, the VisionPad 3200 and VisionPad 3500 take advantage of unique chemistries that improve die yields by minimizing scratches, chatter marks
and other defects across the wafer.
The SP2XP detects and separates LLPD faceted pits (also called air pockets or air bubbles) from other defects such as micro-scratches, chatter marks
, and particles.
Its specially-engineered PVC formulation minimizes chipout and chatter marks
By using a new group of polymer chemistries, the advanced pad technology improves die yields through minimization of scratches and chatter marks
across the wafer.
In addition, the interlamellar cut seems to eliminate the abrasive, planar cut of metal blades with the resulting rough surfaces, debris remnants and chatter marks
