  • Functional Feature Description
  • Technical Application
  • Equipment Parameter
    • • GNAD-T series precision polishing system has independent control system, the whole machine anti-corrosion.
      • All parameters of the host machine can be set on the control system.
      • The jig is equipped with digital thickness monitoring device and an independent drive system, the swing speed and amplitude can be adjusted.
    • • The wafer samples are absorbed on the bottom of the jig by vacuuming, and can be customized according to the user process requirements of various angle and other non-standard jig accessories, to achieve the non-standard shape sample and angle polishing.
      • The rotation speed of the lapping and polishing plate can be adjusted, and the replacement is convenient, greatly shortening the process time.
      • Multi-channel feeding system, the Abrasive Autofeed Cylinder has the function of online stirring when working, and the drop rate can be accurately controlled.
    • • Polishing plate has online real-time temperature control and cooling optional function, when close to the preset temperature warning value, the equipment will automatically start the cooling function, to keep the polishing plate operating within the temperature range required by the process.
      • Polishing plate automatic washing optional function, can be real-time online washing polishing work area. And flow rate, cleaning time and other parameters can be precise numerical control.
      • Device timing function, preset time 0-10 hours. When the preset time is reached, the device will stop automatically.
    • Applicable materials include:
      • Silicon-based materials (Si, a-Si, poly Si)
      • III-V materials (GaAs, InP, GaSb, etc.)
