MTSN Mattson Technology, Inc.

Mattson Technology, Inc. (NASDAQ: MTSN), a leading supplier of advanced process equipment used to manufacture semiconductors, today introduced SUPREMA® XP5, its latest photoresist dry strip system designed to deliver the extendibility, performance, cost of ownership (CoO) and reliability that chipmakers require for high-volume production of current and future-generation logic, DRAM and flash memory devices. This newest addition to the company's family of innovative products is based on the production-proven, vacuum-based, high-throughput SUPREMA platform and proprietary Faraday-Shielded Inductively Coupled Plasma (ICP) source technology. SUPREMA XP5 provides the most flexible and cost-effective solution for advanced front-end-of-line (FEOL) and back-end-of-line (BEOL) strip applications using oxygen-based process chemistries.

"The introduction of SUPREMA XP5 reinforces Mattson Technology's commitment to delivering high-performance, reliability and productivity systems to our customers as they look to extend strip technology to advanced nodes," said Rene George, vice president and general manager of Mattson Technology's Plasma Products Group. "SUPREMA XP5 builds on Mattson Technology's production-proven SUPREMA platform and provides the best processing performance and CoO to meet current and next-generation requirements of oxygen-based process applications. This new product offering allows our customers to address their latest technological challenges without sacrificing reliability or productivity and further strengthens Mattson Technology's leading position in the strip market."

About SUPREMA XP5 The SUPREMA XP5's modular platform utilizes a simplified vacuum-based wafer transfer architecture designed to meet next-generation strip requirements with improved CoO, increased reliability and best-of-class particle performance to meet next-generation cleanliness requirements. The system features a simplified, combined vacuum loadlock and transfer module with a unique architecture to enable faster time to production and reduce the use of moving and consumable parts to lower chipmakers' total capital costs. SUPREMA XP5 provides the capability to run recipes at higher source power and features improved system packaging to simplify and lower costs related to installation, maintenance and serviceability.

SUPREMA XP5's patented Faraday-Shielded ICP source technology provides the industry's widest process window to achieve superior on-wafer processing results with the highest strip rates available today. Designed to address all oxygen-based strip process requirements, SUPREMA XP5 features reliable, high-speed vacuum and atmospheric robotics to deliver higher productivity with throughput of greater than 430 wafers per hour. The SUPREMA XP5 is positioned to set a new benchmark for strip performance, with exceptional process flexibility, efficiency, reliability and CoO for high-volume manufacturing of advanced chips down through the 2X nanometer (nm) node.
