    2018-8-25 · Also, silicon nitride being significantly harder than SiO2, the silica particles tend to roll over the surface due to the slurry flow and show lesser te ndency for indentation. This causes lesser shear for a given down force, which in turn implies that COF values when Si3N4 is polished by silica ILD slurry are lesser as compared to SiO2.
