AE to Feature Aera^® PI-980^™ Series Pressure-Insensitive MFC for Advanced Processes at SEMICON China 2006

SHANGHAI, China, March 14, 2006—Advanced Energy Industries, Inc. (Nasdaq: AEIS) today announced that it will feature its Aera^® PI-980^™ series pressure-insensitive mass flow controller (MFC) during SEMICON China 2006. The company also will showcase its Navigator^™ Digital Matching Network and the Litmas^™ RPS 1501 and 3001 remote plasma source platform at the exposition, held March 21-23 at the Shanghai New International Expo Center (SNIEC) in Shanghai, China.

The Aera PI-980 series pressure-insensitive MFC is especially well-suited for etch, CVD, PVD, and diffusion applications, delivering faster response, greater gas-flow stability, higher accuracy, and better real-time process control than previous technologies or competitive products. Specifically, its superior gas-flow stability provides greater chamber-to-chamber process repeatability for improved production yields. The advanced design of the PI-980 integrates traditional thermal flow architecture with a pressure sensor, pressure display, temperature sensor and NeuralStep™ control technology, creating a single delivery package and eliminating the need for the costly gas-panel components traditionally used to perform the same function.

In addition, the Navigator Digital Matching Network will be exhibited at AE’s booth #2326. The Navigator, which is equipped with microprocessor-controlled stepper motor circuitry and digital, user-selectable tuning algorithms, minimizes reflected power by automatically tuning the complex impedance of a coupled plasma. For real-time measurement and analysis of process power and impedance, the optional, internal Z’Scan^® RF sensor enables the user to identify and significantly reduce process variability.

Also showcased this year will be AE’s Litmas RPS 1.5 kW and 3 kW integrated plasma source and power-delivery systems. The Litmas RPS is the only fully integrated, remote, inductive plasma source and power delivery system available in a high-conductance, low-surface-area geometry. It is well-suited to deliver reactive gas specie fluxes for process applications such as wafer pre-clean, photoresist strip and thin-film deposition.
