Gas Monitor IR-400

High-grade type Gas Monitor for Chamber Cleaning End Point Monitoring

The IR-400 offers real-time monitoring of the chamber cleaning end point during the deposition process. By optimizing the cleaning process, the IR-400 reduces cleaning time and gas usage. This reduction in cleaning gas usage leads to a reduction in chamber damage and increases the life times of all the systems components.

Measurement Techniques

Reliable, High-performance
Non-dispersive Infrared Absorptiometry (NDIR)

The infrared absorptiometry method employed by the IR-300 Series uses the principle of the absorption by gas molecules of the infrared light emitted from an infrared light source. A sample output from a sample that has absorbed the gas being measured is compared to a reference output with no absorbance, and the result is converted into a gas concentration. The use of this double beam method enables long-term, stable measurement results to be obtained.

Reliable, High-performance Non-dispersive Infrared Absorptiometry (NDIR)

 

The optical system is made up of a light source, gas cell and double beam detectors. The stability of the double beam detector has been proven over a period of more than 40 years.
