Very High Precision Spindle


Semiconductor metrology systems builders

Very high resolution optical encoder and precision rotation allows very stable speed control.

Used for:

High precision electro-optical metrology systems used for semiconductor manufacturing processes inspection.

Main features and advantages

  • Smooth and precise air bearing
  • Super low run-out of rotating axis to 0.25 pm
  • “0” cogging electric motor design
  • Clean operation meets class 2 dean-room environment standard
  • Uses specially designed vacuum system to eliminate any air flow from bearing to the environment
