Abstract

Methods for fabricating a chemical-mechanical polishing composition include growing colloidal silica abrasive particles in a liquid including an aminosilane compound such that the aminosilane compound becomes incorporated in the abrasive particles. A dispersion including such colloidal silica abrasive particles may be further processed to obtain a chemical-mechanical polishing composition including colloidal silica particles having the aminosilane compound incorporated therein.
