    Abstract: The invention provides a chemical-mechanical polishing composition comprising (a) wet-process ceria abrasive, (b) a surfactant comprising an amine-containing anchor group and ethylene oxide-propylene oxide stabilizing group, wherein the surfactant has a molecular weight of from about 1000 Daltons to about 5000 Daltons, (c) an aromatic carboxylic acid or heteroaromatic carboxylic acid, and (d) water, wherein the polishing composition has a pH of about 3 to about 6. The invention further provides a method of chemically mechanically polishing a substrate with the inventive chemical-mechanical polishing composition. Typically, the substrates contain silicon oxide.
