Electrostatic Chuck power supply
Fast Response, Dual Output Rack Mount Power Supply
- ±1 kV to ±10 kV
- 6 W, 10 W, 30 W
- Single ch output
- 2 ch output (Some models)
RACKMOUNT and SINGLE/2-CH BIPOLAR OUTPUT ±1kV to ±10kV/5W, 6W, 10W, 30W
The ECA series is a high-voltage power supply engineered specifically for electrostatic chuck (E-Chuck) applications. It enables wafer holding and releasing via DC output control, with smooth release achieved through polarity reversal. The series supports both unipolar (2-channel) and bipolar systems, making it a versatile choice for various processes. Its wide output range of ±1 kV to ±10 kV ensures compatibility with both Johnsen-Rahbek and Coulomb type chucks.
FEATURES AND BENEFITS
- Specially designed for Electrostatic Chuck (E-Chuck, ESC) application
- Dual output channels
- Bipolar output
- Built-in RF filter is available. (option)
- Fast response (100 ms) with amplifier structure
- Long life and high reliability due to relay-free polarity switching
