ATMI Japan and Nissan Chemical Announce Manufacturing Agreement

  DANBURY, Conn. and TOKYO, Dec. 3 /PRNewswire/ -- ATMI Japan K. K., a  wholly-owned subsidiary of ATMI, Inc. (Nasdaq: ATMI) and Nissan Chemical  Industries, Ltd. today announced the signing of an agreement granting Nissan  Chemical an exclusive right to manufacture, distribute, and sell certain of  ATMI's wafer cleaning chemicals in Japan.  ATMI provides specialty materials  and services to the worldwide semiconductor industry. Nissan Chemical  specializes in chemical manufacture and has developed a strong market presence  in electronic materials in Japan and Asia.   ATMI and Nissan Chemical have cooperated for three years to introduce ATMI  photolithography residue remover and wafer cleaning chemicals to Japanese  semiconductor and micro-electromechanical systems (MEMS) device manufacturers.  Japan-based manufacturing is an important element of ATMI Japan's strategy to  serve the domestic customer. Qualification of the first phase of Nissan  Chemical's manufacturing plant in Toyama is complete; the plant is expected to  be fully operational in September 2002.   ATMI has developed numerous proprietary cleaning chemical solutions in  response to customer requirements. The formulations are optimized for advanced  designs and for use with emerging copper and low-k-based semiconductor  technologies. Several major semiconductor manufacturers in Asia and Japan have  selected ATMI's unique cleaning chemistries for copper and low-k commercial  production.   The semiconductor manufacturing process modifies wafers by stacking  multiple chemical layers by numerous processes, which include thin film  chemical or physical vapor deposition, ion implantation, and photolithography.  Producing a completed semiconductor "chip" on a wafer may take more than  400 discrete process steps. The wafers need to be carefully cleaned with  specialty cleaning materials that selectively remove only unwanted materials  prior to starting each new step. Underlying circuits must be left untouched  when cleaning and removing extraneous particles and residues.   Nissan Chemical offers a wide range of unique products and materials  through a combination of traditional chemical synthesis and cutting-edge  technology. Outside of a strong presence in the LSI (large scale integration)  market with unique antireflective coatings and in the LCD market with unique  orientation layer materials, Nissan Chemical has a renowned presence in  agrochemicals, pharmaceuticals, and a variety of specialty chemicals. Nissan  Chemical has created added value to their target markets through intensive  research and development efforts.   ATMI provides specialty materials and services to the worldwide  semiconductor industry.   Located in Tokyo, ATMI Japan promotes ATMI products and services in  cooperation with its partners and provides selected ATMI products and services  to the semiconductor manufacturers. Nippon Sanso and ATMI are partnered to  provide safer and more productive process gas delivery systems; Nissan  Chemical and ATMI are partnered to provide liquid solutions used in cleaning  semiconductor wafers; Sanyo Chemical and ATMI are partnered to provide  chemical mechanical polishing (CMP) slurries.   Statements contained herein that relate to ATMI's future performance,  including, without limitation, statements with respect to ATMI's anticipated  results of operations or level of business for 2001 or any other future  period, are forward-looking statements within the safe harbor provisions of  the Private Securities Litigation Reform Act of 1995. Such statements are  based on current expectations only and are subject to certain risks,  uncertainties, and assumptions, including, but not limited to: changes in  semiconductor industry growth or ATMI's markets; competition, problems, or  delays developing and commercializing new products; problems or delays in  integrating acquired operations and businesses into ATMI; problems or delays  associated with any restructuring activity; and other factors discussed in  ATMI's filings with the Securities and Exchange Commission. Such risks and  uncertainties could cause actual results to differ from those projected. ATMI  undertakes no obligation to publicly update or revise any forward-looking  statements, whether as a result of new information, future events or  otherwise.
