Variable-Frequency Generator For PVD, CVD, and ETCH now available from Advanced Energy

June 3, 1999—A cost-reduced 3000 W variable frequency generator designed primarily for use with 200 mm and 300 mm wafer processing equipment has been introduced by Advanced Energy Industries, Inc. (Nasdaq: AEIS). The new HFV-L is especially suited for PVD, PECVD, etch, and other inductively coupled plasma (ICP) applications.


The HFV-L provides flexibility though digitally-synthesized variable frequency output and microprocessor control. The output frequency range is 1.765 MHz to 2.165 MHz. Frequency tuning parameters that reside in firmware may be customized to ensure reliable operation with a wide variety of chamber configurations and process recipes.


  • 2 MHz, digitally synthesized variable frequency
  • Load power or forward power regulation modes
  • 3 kW output level
  • Internal diagnostics to verify proper operation
  • Standard rack dimensions with 5¼-inch height
  • Water cooled for reliable and consistent operation

Copies of the brochure describing these variable frequency generators are available at no charge by sending a request via e-mail to or from the web at
