s-Optius

Enable to monitor the situation of various processes in real time by measuring an emission spectrum of the plasma. Optimum for feedback control of the MFC by the reactive sputtering process and endpoint detection of the etching process.

Features

  • Broad measurement wavelength
    Measurement wavelength range is 200 to 1000nm, it is also possible to measure simultaneously specified multiple wavelengths
  • Simultaneous measurement of up to 5ch
    Addition of the Expansion unit (ESC) options enable simultaneous measurement of up to 5ch
  • Feedback control
    Feedback control of external equipment by measurement result.
  • Exclusive software
    Exclusive software corresponding to multiple processes including the reactive sputtering and etching is included.
  • Two kinds of light receiving units
    Receiver unit can be selected from atmosphere type or vacuum type depending on the application.

Applications

  • Feedback control of MFC and process monitoring in reactive sputtering
  • Endpoint detection by the plasma etching process
  • Confirmation of the cleaning and initialization status of Etching and CVD equipments
