100th Suprema(TM) Strip Tool Ships to Leading Semiconductor Foundry, WXIC FREMONT, Calif., March 20 /PRNewswire-FirstCall/ -- Mattson Technology, Inc. (NASDAQ:MTSN), a leading supplier of advanced semiconductor process equipment used to manufacture Integrated Circuits or IC's, today announced that the Company has shipped its 100th Suprema(TM) photoresist strip system within just two years of the official introduction of the product. The 100th Suprema system was shipped to Wuhan Xinxin Semiconductor Manufacturing Corporation, China; one of the newest 300mm semiconductor foundries in the world, which is operated and managed by Semiconductor Manufacturing International Corporation (SMIC). The system is being installed in WXIC's 300 mm facility. The shipment expands Mattson's installed base of Suprema systems and is a continuation of its market leadership with photo resist strip products. Suprema Performance Highlights -- Suprema is rapidly displacing competitors and winning in both established and new accounts. This success is attributable to the system's advanced technical performance and compelling Cost of Ownership (COO) gains for Mattson's customers. -- The Suprema has been installed and is operational at 8 of the top 10 global semiconductor companies, and is being used for high volume production as well as sub-45nm process development. -- Mattson's superior operational efficiency gains have resulted in faster Time-to-Market. -- Suprema product adoption by Mattson's customers is the fastest product ramp in Mattson history, exceeding previous strong ramps of Aspen 3(TM) and Helios(TM) products by 200%, or a 50% reduction in the time required to get the product to market. "China is an important force in the development of advanced technologies and the global IC market, generating the most worldwide sales of ICs;" noted David L. Dutton, chief executive officer of Mattson Technology, "and we are very pleased to be working with Wuhan Xinxin Semiconductor, one of the newest 300mm semiconductor foundries in the world. This milestone shipment expands the Company's installed base of Suprema systems, continues our market leadership with photoresist strip products, and further positions Mattson to outperform the industry. It is a validation of the Company's superior technology and competitive advantages, which we believe will continue to displace competitors and will drive market share gains for Mattson." John Liu, vice president of the Wuhan project at SMIC, commented, "We selected the Suprema system due to its extremely high productivity with superior process performance, low COO and reliability. As the first 300mm fab in central China delivering advanced technologies, we seek partners who can contribute to improved efficiencies, economics and performance. Mattson Technology is a valued partner with the requisite dedication to improvements in their customers' productivity." Sr. Vice President and General Manager of Mattson Technology's Surface Cleaning Group, Neal Holmlund, said, "The success of Suprema is a testament to the extremely high reliability and throughput of the product, coupled with enabling process performance, maturity and extendibility to future technology nodes. Wuhan Xinxin Semiconductor has selected the Suprema system including for advanced High Dose Implant Strip or HDIS applications -- demonstrating their confidence in the system's ability and maturity to deliver the process expandability that can help speed critical time-to-market for Wuhan Xinxin Semiconductor's current and future products. We look forward to further supporting our customer as they ramp up production capacity for the company's state-of-the-art 300 mm fab." About Suprema(TM) The Suprema(TM) product was first introduced by Mattson Technology on January 30, 2006. The system combines Mattson's proprietary inductively coupled plasma (ICP) technology with an innovative handling architecture.
