Abstract
In this paper, we suggest a novel evaluation method of translational Brownian motion of nano-abrasives in CMP slurry. The slurry is complex composite and the viscosity is not uniform during the translational motion of nano-abrasives. We apply the fluorescence anisotropy analysis to measure the integration of viscosity. The viscosity for the area where the abrasive nano-particles passing through in their translational motion is integrated in order to determine the average of the translational diffusion coefficient.
