ELECTROSTATIC CHUCK POWER SUPPLY
Wafer Sensor adopted
- Max Voltage:±0.5 to ±7.5 kV
- Max Current: 1 to 20mA
- Dual-channel independent output
- Compact half-rack size design
Two channels, reversible, floating, programmable high voltage power supply for electrostatic chuck drivers.
HECD series is a dual-channel, reversible, floating, programmable high voltage power supply for electrostatic chuck drivers. In addition to the polarity switching and forced grounding, the series offers a wafer monitoring system to satisfy wafer detection needs. Furthermore, with the wide range of voltages, this series can support both coulombic and Johnsen-Rahbek electrostatic chucks.
FEATURES AND BENEFITS
- Half rack size compact design
- Polarity reverse enabling increased throughput with quick dechucking
- Reliable chucking and releasing status detection via wafer sensor
- Fast response achieved through amplifier architecture design, ensuring high reliability and long lifespan due to 'non-relay polarity reversal' design.
- "Optional independent control for dual channels" and "Optional center-tap voltage setting" for various chuck/dechuck operations
- Digital interface with LAN, USB, RS-232C, or Ether CAT (option)
- Built-in 13.56 MHz RF filter
- Selectable models for wafer size and your applications
- OEM available (4-ch, 6-ch, digital communication, another output power)
APPLICATIONS
- Electrostatic Chuck (E-Chuck, ESC)
- Semiconductor Fabrication Equipment
- Photolithography
- Chemical vapor Deposition (CVD)
- Plasma Enhanced CVD (PECVD)
- Semiconductor wafer handling
- Flat panel handling
- Dry etching
- Plasma etching
- Reactive-ion etching (RIE)
