WebApr 10, 2024 · The colloidal silica slurry (CMP slurry) with a particle diameter of 80 nm and diluted to a concentration of 20 wt% was applied onto the pad. The viscosity of this CMP slurry is approximately 1.4 mPa s (measured using the Cannon–Fenske viscometer), approximately the same as that of pure water. WebMonitoring slurry density ensures the right blend is delivered to the process tools. For monitoring incoming slurry, densitometry has become the common method. Variations in density indicate a non-uniform slurry (i.e., a higher concentration of large particles is possible at any given time), which can affect the removal rate and lead to defects.
