Applied Materials Acquires ATMI's Treatment Systems Business; Acquisition Extends Applied's Expertise in Providing Environmental Solutions.

SANTA CLARA, Calif. -- Applied Materials, Inc. (Nasdaq:AMAT) today announced that it has purchased the assets of ATMI, Inc.'s Treatment Systems business for an undisclosed cash amount. The business will be operated as a division of Metron Technology, Inc., a wholly-owned subsidiary of Applied Materials and will continue to support the gas abatement requirements of current and future process equipment for semiconductor manufacturing and other industrial applications.

"ATMI's effluent treatment products are a natural extension of Applied Materials' recognized leadership and long-term commitment to providing environmentally responsible solutions to the semiconductor manufacturing industry," said Russell Ellwanger, group vice president and general manager of Applied Global Services. "This acquisition, combined with Applied's core process knowledge and extensive environmental expertise, allows us to provide a broad range of optimized environmental abatement solutions to customers for multi-vendor systems and applications."

ATMI's Treatment Systems Division is a worldwide leader in providing point-of-use abatement systems to the semiconductor industry that treat gas emissions from process chambers before they are released to the environment. These systems include dry, wet, thermal and integrated thermal/wet technologies.

As part of Metron Technology, the Treatment Systems Division will have access to Applied Materials' significant portfolio of environmental solutions and resources for developing best of breed systems that maximize efficiency, enable rapid cycle time for new processes and chemistries, and assure global environmental regulatory compliance for its customers.

"Reducing hazardous air pollutants, volatile organic compounds and global warming gases is a critical objective for Applied Materials and its customers," said Werner Finsterbusch, general manager of Metron Technology. "Our acquisition of ATMI's abatement equipment business provides us with an excellent opportunity to work together with our customers to help assure environmental compliance of processes and products worldwide."
