Advanced Energy Unveils Aera® PI-980(TM) Pressure-Insensitive MFC with NeuralStep(TM) Control Technology

Next-generation pressure-insensitive MFC for etch, CVD, PVD and diffusion processes enables exceptionally fast response and higher yields

FORT COLLINS, Colo., July 5, 2005-Advanced Energy Industries, Inc. (Nasdaq: AEISE) today unveiled its next-generation Aera® PI-980(TM) series of pressure-insensitive mass flow controllers (MFCs) for advanced semiconductor applications. Designed to improve processes for etch, CVD, PVD and diffusion, the PI-980 MFC's innovative technology provides greater gas-flow stability, higher accuracy, exceptionally fast response and superior real-time process control. Its highly stable flow delivers greater process control and repeatability, maximizing production yields.

The PI-980 series complements the recently released Aera Transformer(TM) 780/7800 series of digital MFCs, allowing fabs and OEMs to standardize on the latest technologies from Aera across multiple process steps and varied application requirements.

By combining exceptionally fast NeuralStep(TM) control technology with an integrated pressure transducer, the PI-980 MFC dramatically increases the speed of the MFC response. This increased speed virtually eliminates the effects of upstream and downstream pressure disturbances. Faster response delivered with excellent flow stability enable shorter process steps, stable chamber-gas delivery, higher accuracy, higher repeatability and a wide, multi-gas control range. The result is optimized process performance and maximized yields.

Further, the PI-980 MFC enhances overall system cost of ownership by eliminating the need for a number of traditional, costly gas-panel components. Its multi-gas, multi-range functionality dramatically reduces inventory requirements.

Steve Rhoades, executive vice president, Products and Operations, noted, "Our new PI-980 MFCs with NeuralStep technology are a best-in-class addition to Aera's world renowned line of MFCs. This is a great example of AE's continuing commitment to technology innovation. It's also a great example of AE's continuing commitment to increasing our customers' competitive advantage."
