Nanophase to Present at NANOMATERIALS 2004

October 12, 2004 Posted by Nanophase Technologies Corp.


Nanophase Technologies Corporation, a technology leader in nanomaterials and nanoengineered products, today announced that it is scheduled to present, “The Emerging Role of Nanocrystalline Ceria in Microelectronic Glass Polishing Applications” at the “Best Submitted Papers” session of NANOMATERIALS 2004: Nanoelectronics, Nanophotonics, and Nanomagnetics (25-26 October 2004), Stamford, CT. Current roadmap requirements for microelectronic devices are driving increasingly demanding specifications for chip planarity and defectivity in the CMP area, but this is also placing stringent new performance specifications on laser lenses, lithography optics, and photomask blanks. As a result, every glass surface that the laser light contacts en route to generating a circuit image on the wafer must be polished to higher tolerances.

Dr. Richard Brotzman, Nanophase’s Vice President of R&D, will discuss a new glass polishing particle and dispersion technology that Nanophase recently developed to address these technical requirements—a comparatively smaller, more chemically active particle, with tighter particle size distributions, high purity, and improved commercial consistency. These materials are manufactured by Nanophase’s patented NanoArc(TM) process and are now commercially available as ceria and alumina dispersions. The differentiating characteristics of these nanomaterials which enable polishing applications will be discussed.

Dr. Ed Ludwig, Nanophase’s Vice President of Business Development, stated, “Nanophase has the quality systems and commercial capability to deliver state- of-the-art polishing dispersions in high volume with outstanding stability. This illustrates our ability to develop enabling technology and to bring value to our customers and partners by engineering solutions to specific market needs.”
