Abstract
Stick-slip friction is one of the material removal mechanisms in tribology. This stick-slip friction occurs when the static friction force is larger than the dynamic friction force, and make the friction curve fluctuated. In the friction force monitoring system for chemical mechanical polishing(CMP), the friction force also vibrates just as stick-slip friction. It seems that the stick-slip friction causes scratches on the surface of moving parts. In this paper, A study on the scratches which occur during copper CMP was conducted in a view of stick-slip friction.
