FORT COLLINS, Colorado (November 7, 1997)—Greg Roche has been named Applications Development Manager for Advanced Energy Industries, Inc. (AE). In announcing the new appointment, AE’s Vice President for Marketing, Sales, and Global Support Jim Gentilcore said, “We’re glad to have someone with Greg’s background in plasma processing to help our marketing and development efforts as we strive to find new opportunities outside of our existing products to keep our rapid growth rate on course.” Mr. Roche will report directly to Mr. Gentilcore.

Before joining Advanced Energy on October 6, Mr. Roche spent four years at Lam Research, most recently working on process development for PECVD (plasma enhanced chemical vapor deposition).

Upon joining AE, Mr. Roche said, “I’m excited about expanding process capability at AE. We intend to utilize the Applications Lab to characterize our current and future products under plasma conditions similar to those seen in our customers’ equipment. This information will be used to assist our customers in optimizing their processes and to foster our development of new products.”

Founded in 1981, AE is a leading supplier of power conversion and control systems for plasma-based thin film production equipment. Our systems are critical to industrial processes that use gaseous plasmas to deposit or etch thin film layers on materials or substrates such as glass, silicon, and metals during the manufacture of semiconductors, data storage media, flat panel displays, and a host of other products.
