The Semiconductor industry mandates precise quality and uniform control over temperature and wafer handling. Our solutions are integrated into Wafer and OLED fabrication equipment in these specialties:

  • Temperature measurement in RF plasma enhanced etch
    During wafer fabrication in dielectric etch, temperatures within the electrostatic chuck are carefully maintained and monitored for complete stability.
  • Positioning sensing of wafer handling in all semiconductor processes
    At any step during wafer fabrication, high-accuracy position sensors are critical for wafer handling to and from the fab equipment.
  • Flat Panel Display
    Etch and Deposition in OLED manufacturing process applications rely on fiber optic temperature sensors for precise process control in high RF (radio frequency) environments.
