Slurry abrasive
Webb12 juli 2014 · Slurry plays an important role in the material removal of chemical mechanical polishing (CMP). However, the behavior of abrasive particles of the slurry in the interface between the wafer and the pad during CMP is not fully understood. In this paper, a new computational fluid dynamic (CFD) model was developed. Webb1 feb. 2014 · As the most potential slurry abrasives in chemical mechanical polishing (CMP), cerium oxide (CeO2) nanoparticles have the advantages of high material removal rate and high selectivity of oxide and nitride [1].
