Modeling of Polishing Pad Wear in Chemical Mechanical Polishing

扫码查看
The polishing pad's wear influences the surface accuracy of the polished wafer. A new polishing pad wear model is established using the idea of Finite Element Analysis (FEA) and the effect of polishing parameters on the wear of polishing pad is discussed.
