The slurry composition according to the invention can be used to polish glass and glass ceramics at a high removal rate, but does not hard settle upon extended static conditions and can be easily resuspended. The present invention also provides a method of polishing a glass or glass ceramic substrate using the slurry composition.Type: GrantFiled: May 22, 2003Date of Patent: November 27, 2007Assignee: Ferro CorporationInventors: Steven A.

Patent number: 7229484Abstract: The present invention relates to the manufacture and use of novel pre-coated abrasive particles and particle slurries for the chemical mechanical polishing (CMP) of semiconductor wafers, thin films, inter-layer dielectric, metals, and other components during integrated circuit, flat panel display, or MEMS manufacturing. For example, polishing slurry abrasive particles can be pre-coated with additives, such as, inhibitors and/or surfactants during manufacture of the abrasive particles or slurry. The additive's opportunity to react directly with the abrasive particles early in the particle manufacturing process provides a slurry having a more stable, selectable, and predictable ratio of abrasive particles pre-coated with a more stable, selectable, and predictable amount and type of additives.Type: GrantFiled: November 27, 2002Date of Patent: June 12, 2007Assignee: Intel CorporationInventors: Reza M.
