  • Alumina abrasive for chemical mechanical polishing
    Patent number: 7344988
    Abstract: Methods of manufacturing alumina abrasive for use in chemical mechanical polishing are described, wherein the abrasive is in a slurry having gamma alumina formed in a low temperature fuming process, water, an acid sufficient to maintain the pH below about 7, wherein the slurry does not settle appreciably in an 8 to 24 hour period. Advantageously, the alumina is wet-milled without the use of wet-milling salt additives.
