Photon Control’s Fiber Optic Temperature Sensors

Our fiber optic temperature sensors are used to measure the electrostatic chuck temperature in plasma etch systems

• The measured temperature is used to maintain a uniform wafer temperature during processing

Why does temperature uniformity matter?

• The performance of an individual chip is very sensitive to the local wafer temperature

• More sensors and higher accuracy sensors enable better wafer temperature control which produces higher yield

• Photon Control’s current accuracy specification is +/-0.5oC
