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.
- Multi gas monitoring (Supported SiF4 andCF4) (IR-422)
- High sensitivity
- Gas cell heating function up to 180 dec.C
- Multi-display
- Analog/Digital communication.
Benefits of real-time end-point monitoring with the IR-400
- Reduce time for chamber cleans
- Reduce usage of cleaning gases
- Repeatable and predictable clean process
- Longer lifetime of chamber components
Applications example
- Monitoring chamber exhaust line
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.
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.
