Navigator^® II FastCap™ Solid-State Technology Provides Fastest Matching for Sub-22 nm Semiconductor Processes

San Francisco, Calif., July 10, 2012—Advanced Energy Industries, Inc. (Nasdaq:AEIS), a leader in power conversion solutions, today announced the introduction of the Navigator^® II FastCap™ matching network. The latest extension of the Navigator platform, the FastCap matching network breaks new ground by providing the fastest matching available for next-generation thin-film plasma processes. The new product will be featured this week at the Advanced Energy product showcase during the SEMICON^® West tradeshow in San Francisco.

Yuval Wasserman, president of Advanced Energy Thin Films, said, "Over the last decade, our digital matching technology and industry-exclusive tune-while-pulsing capabilities set new standards in RF power conversion with over 15,000 units installed worldwide. Now, with the launch of the Navigator II FastCap, our innovation in solid-state matching technology provides the fastest tuning times in the industry, addressing the increasing demand on process predictability and reproducibility in sub-22 nm technology nodes."

The Navigator II FastCap addresses the need for high-speed matching using a patented hot-switchable capacitor arrays in place of conventional vacuum capacitors, producing significant tune-time advantage, and reducing tuning times to as little as 2 msec. The FastCap solution is qualified for use with AE's Paramount^® line of RF power supplies. Currently under evaluation at several major OEMs, this product is available for further evaluation on most common low-power PECVD and etch bias applications. General product availability with expanded power and frequency ranges are planned for release in 2013.
