摘要: Chemical mechanical polishing compositions include modified silanized colloidal silica particles which are reaction products of silanized colloidal silica particles having epoxy moieties with nitrogen of amines to form stable and tunable modified silanized colloidal silica particles. The modified silanized colloidal silica particles can be used as an abrasive in chemical mechanical polishing of various substrates to polish metal such as copper, Ta and TaN and dielectrics such as TEOS and low-K film.
