E-Chuck High Voltage Power Supply

Halfrack width space-saving design

  • ±1 kV to ±5 kV
  • 30 W
  • Single channel output
  • Fast response model

SINGLE CHANNEL, BENCHTOP BIPOLAR TYPE ±1 kV TO ±5 kV/6 W, 30 W

The EJC series is a benchtop high-voltage power supply engineered specifically for electrostatic chuck (E-Chuck/ESC) applications. Its bipolar output capability allows for smooth wafer release by reversing polarity, eliminating the need for mechanical relays. With a wide voltage range of ±1 kV to ±5 kV, the series supports both Coulomb and Johnsen-Rahbek force applications.

FEATURES AND BENEFITS

  • Designed specifically for Electrostatic Chuck (E-Chuck/ESC) applications
  • Fast response (100 ms) enabled by high-speed amplifier design
  • Bipolar output for efficient clamping and declamping
  • Optional integrated RF filter
  • Relay-free design ensures high reliability and long service life
