Abstract
Particle’s behavior in the slurry with power-law viscosity shows great effect on the wafer surface polishing. Hydrodynamic pressure is periodically generated on the surface asperity when particles are passing through it. Fatigue fracture occurs under the effect of periodical pressure and it begins from the top to the bottom of the asperity. Based on the energy-balance fracture theory, the removal rate is calculated and it shows good agreement with experiment data.
