Patent number: 8304344Abstract: A chemical mechanical polishing process including a single copper removal CMP slurry formulation for planarization of a microelectronic device structure preferably having copper deposited thereon. The process includes the bulk removal of a copper layer using a first CMP slurry formulation having oxidizing agent, passivating agent, abrasive and solvent, and the soft polishing and over-polishing of the microelectronic device structure using a formulation including the first CMP slurry formulation and at least one additional additive. The CMP process described herein provides a high copper removal rate, a comparatively low barrier material removal rate, appropriate material selectivity ranges to minimize copper dishing at the onset of barrier material exposure, and good planarization efficiency.Type: GrantFiled: February 5, 2008Date of Patent: November 6, 2012Assignee: Advanced Technology Materials, Inc.Inventors: Karl E.

Publication number: 20100189663Abstract: Novel mouth rinse (i.e., mouthwash) compositions that permit delivery of silica or silicate materials to the surface of teeth through common mouth rinsing procedures are provided. Such compositions must exhibit proper suspension of the silica or silicate materials (in particulate form) to prevent settling during storage while simultaneously providing proper mouth rinsing properties. Such silica or silicate materials may themselves exhibit any number of therapeutic or aesthetic benefits as long as such materials are easily transferred through mouth rinsing and exhibit proper affinity for deposit on target teeth upon contact therewith. Such silica or silicate materials should exhibit, in one embodiment, certain ionic charge levels as well as sufficiently small particle sizes to permit effective static attraction and eventual accumulation on target tooth surfaces.Type: ApplicationFiled: December 29, 2009Publication date: July 29, 2010Inventors: Karl W.

Publication number: 20090211453Abstract: Novel acid-impregnated silica materials for use as environmental controls in air handling systems where highly efficient removal of ammonia and volatile amines from gaseous streams is required (e.g. clean rooms) are provided. Such silicas exhibit specific porosity and density measurements to provide a satisfactory support for an acid impregnant incorporated subsequent to initial solid silica particle production, in order to provide effective ammonia bonding sites. The combination of the silica support properties and the acid impregnant permits highly effective ammonia (or volatile amine) gas removal, resulting in excellent noxious gas removal efficiencies and capacities, particularly in comparison with prior media filtration products. Methods of using such acid-impregnated silica filter media and specific filter apparatuses are also encompassed within this invention.Type: ApplicationFiled: February 26, 2008Publication date: August 27, 2009Inventors: Terry W. Nassivera, Fitzgerald A. Sinclair, Michael S. Darsillo, Ruth G. Heffes
