ELECTROSTATIC CHUCK POWER SUPPLY
Integrated Wafer Sensor
- Max Voltage：±0.5 to ±7.5 kV
- Max Current: 1 to 20mA
- Dual-channel independent output
- Compact half-rack size design
Dual-channel, reversible, floating output high-voltage power supply for electrostatic chucks.
The HECD series is a programmable high-voltage power supply designed specifically for electrostatic chuck (ESC) applications. It features dual-channel floating outputs with polarity switching and forced grounding capabilities. The integrated wafer monitoring system ensures reliable chucking status detection. With a wide voltage range, the HECD series supports both Coulombic and Johnsen-Rahbek type electrostatic chucks.
FEATURES AND BENEFITS
- Compact half-rack size design
- Polarity reversal enables increased throughput with quick dechucking
- Reliable chucking and release status detection via wafer sensor
- Fast response and high reliability achieved through solid-state amplifier architecture (non-relay polarity reversal)
- Optional independent dual-channel control and center-tap voltage setting for versatile operation
- Digital interface options: LAN, USB, RS-232C, or EtherCAT
- Built-in 13.56 MHz RF filter
- Selectable models optimized for various wafer sizes and applications
- OEM configurations available (4-ch, 6-ch, digital communication, custom output ratings)
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)
