Mattson Technology Introduces Helios XP™ and Extends RTP Leadership Into Logic and Foundry Market

Ships Helios XP™ System to a Leading Foundry Customer for Advanced Anneal Processing

FREMONT, CA--(Marketwire - August 31, 2009) - Mattson Technology, Inc. (NASDAQ: MTSN), a leading supplier of advanced process equipment used to manufacture semiconductors, today announced the release of the Helios XP™ system, the company's latest innovation targeted to meet the stringent requirements of advanced rapid thermal processing (RTP) for 45nm node and below. The third generation of 300-millimeter RTP tools strengthens Mattson's RTP market leadership for advanced chip manufacturing, extending its strong memory market position into logic and foundry segments. The company noted that its Helios XP system has been in qualification at a major IC manufacturer and it recently shipped a system to a leading foundry customer for advanced anneal processing.

Senior Vice President and General Manager of Mattson Technology's Thermal Products Group, Andreas Toennis, noted, "We are extremely pleased with the Helios XP's performance against leading customers' most advanced anneal application requirements. Helios XP offers the industry's first RTP processing capabilities at temperatures down to 220 degrees Celsius and below, enabling the advancement of future technology node development including the formation of advanced silicides. In addition, temperature and ambient controls have greatly improved for exceptional within-wafer uniformity and wafer-to-wafer repeatability required for 45nm and below technology nodes."

Toennis continued, "Our customers continue to demand technology solutions required to advance to the next technology node while maintaining the lowest possible cost performance. We listened to those challenges and acted. Even during the industry's worst downturn we invested in advancing the RTP technology providing unique and enabling solutions to the industry. With the introduction of Helios XP, Mattson's RTP position is stronger than ever. Helios XP delivers the advanced capabilities our customers require at the lowest cost-of-ownership, and the shipment of the system to a leading foundry customer is a testament of the traction we are gaining in the leading-edge logic segment. We look forward to working closely with the customer and continue to validate their confidence in Mattson and our capabilities in meeting their advanced process requirements."
