Fort Collins, Colorado (June 2, 2000)-Advanced Energy Industries, Inc. (Nasdaq: AEIS) has introduced the RFSuite(tm) family of advanced power delivery solutions. This unique family of integrated technologies provides power delivery, control and monitoring, as well as process enhancement and diagnostics for etch, PVD, and CVD semiconductor applications. The RFSuite family integrates the sophisticated 13.56 MHz Apex(tm) generator, Navigator(tm) digital match network, Z-Scan(tm) in-situ sensor, and PowerView(tm) control and monitoring software into a highly functional and versatile power delivery solution. This configuration goes beyond traditional RF power delivery systems, which are usually comprised of a generator and match only. The RFSuite family is the most innovative integration of technology available to ignite, maintain, diagnose, and control a plasma process.

The RFSuite family provides a number of critical benefits to the semiconductor manufacturing process including, clean, stable, repeatable process power; real-time predictive film stress; end-point detection; real-time etch rate; improved etch consistency; improved uniformity and film adhesion; tool-to-tool matching; and substantial savings on consumables, such as NF3 and other costly process gases.

Copies of the RFSuite brochure are available at no charge via e-mail to sales.support@aei.com or from the web at www.advanced-energy.com.
