RF power supply for plasma process with 13.56MHz, 0.5kW/1/kW/3kW/5kW output. Compact and lightweight by implementing a high efficiency RF amplifier. RF power supply has a built-in auto matching controller function, power control of the RF power supply and matching system control can be performed with the main unit alone.


  • Uses a high efficiency amplifier
    Energy savings through a construction with an RF circuit featuring good power conversion efficiency.
  • High speed auto matching
    Implements high speed auto matching with a high speed algorithm.
  • RF power generator internally equipped with an auto matching function
    Matching system control is possible with the power generator unit itself. Also capable of manual RF power generator and matching box operations with the internal controller.
  • Supports flexible control configurations
    Capable of external analog and serial communication control.
  • High reliability
    Our accumulated knowledge as an equipment manufacturer has been reflected in the design.


  • Sputtering and CVD
  • Plasma etching
  • RF ion source
  • Neutralizer
