| description | The invention provides a chemical-mechanical polishing composition comprising (a) an abrasive comprising silica particles and alumina particles, wherein the alumina particles are surface coated with an anionic polymer, and (b) water. The invention also provides a method of chemically mechanically polishing a substrate, especially a substrate comprising tungsten, silicon oxide, and nitride, with the polishing composition.
L'invention concerne une composition de polissage chimico-mécanique comprenant (a) un abrasif comprenant des particules de silice et des particules d'alumine, les particules d'alumine étant revêtues en surface par un polymère anionique, et (b) de l'eau. L'invention concerne également un procédé de polissage chimico-mécanique d'un substrat, en particulier un substrat comprenant du tungstène, de l'oxyde de silicium et du nitrure, avec la composition de polissage. |
