Abstract
The effects of the abrasive morphology and surfactant concentration in ceria slurry on removal rates for silicon oxide and silicon nitride films were investigated through a systematic chemical-mechanical-polishing (CMP) experiment. We found that the smaller the abrasives were, the more quickly the removal rates for both oxide and nitride films decreased with increasing surfactant concentration. This result was qualitatively explained by a model in which abrasive particles move through a viscous layer caused by surfactant adsorption onto the film surface being polished.
