DANBURY, Conn., June 25, 2003 — Praxair, Inc. (NYSE:PX), and the H.C. Starck GmbH, an affiliate company of Bayer AG, have formed an alliance to develop, manufacture and supply colloidal silica slurries for the semiconductor chemical mechanical planarization (CMP) market. The market for CMP slurries for semiconductor applications is estimated to be about $350 million in 2003 and is expected to grow at an annual growth rate of 20% over the next five years. The slurries will be marketed and sold globally by Praxair Electronics.
Praxair has been a leading supplier of polishing slurries for the hard-disk data storage and ophthalmic lens markets since 1985, with a manufacturing capacity of 8,000 metric tons per year in Indianapolis, Indiana. In addition to polishing slurries, Praxair produces polishing belts for the CMP market and operates a class 10 CMP polishing lab in Indianapolis to develop, test and customize slurries and polishing media for the semiconductor market.
Bayer was one of the first companies to develop and produce colloidal silica and it has been supplying colloidal silica under the brand name Levasil® for more than 40 years. The annual production capacity of its Leverkusen, Germany facility achieves a five-figure metric ton output making this installation the largest colloidal silica plant in Europe.
Levasil® slurries have been supplied to the silicon wafer polishing market for more than 20 years. Bayer/H.C. Starck have developed a range of products for CMP that covers almost all polishing and planarization steps in semiconductor manufacturing. In 1998, Bayer invested in a dedicated plant for production of CMP slurries with an annual capacity of 5,000 metric tons.
By combining the polishing technology, production and distribution capabilities of Praxair Electronics and H.C. Starck, we substantially enhance our ability to provide value-added polishing solutions to the semiconductor market,” said Mark Gruninger, vice president of Praxair Electronics. “Leveraging the expertise of both companies, we will improve our ability to develop products with a low cost of ownership and to commercialize polishing slurries through Praxair Electronics global sales and marketing organization,” said Dr. Aloys Eiling, Marketing Manager Electronic Chemicals for H.C. Starck.
