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