Measurement of Compressed Air Purity for Semiconductors
We contribute to improving the yield in semiconductor manufacturing. We propose measuring the cleanliness of compressed air.
In the semiconductor industry, the presence of minute foreign substances during the manufacturing process significantly affects product yield. In particular, compressed air is often used in clean rooms, and its cleanliness directly impacts product quality. Contaminants such as fine particles, moisture, oil, and microorganisms can lead to performance degradation of semiconductor devices and the occurrence of defective products. Our company conducts cleanliness measurement and evaluation of compressed air based on standards such as JIS B 8392, supporting yield improvement in semiconductor manufacturing. 【Usage Scenarios】 - Compressed air supply sources in clean rooms - Compressed air supply lines to semiconductor manufacturing equipment - Air blowing on product surfaces 【Benefits of Implementation】 - Reduction in defect rates due to foreign substance contamination - Improvement in product quality - Stabilization of the manufacturing process

Applications/Examples of results
- Measured "liquid oil and oil mist" in the compressed air flowing through the compressed air expansion line at a pharmaceutical manufacturer's factory. Verified that the oil cleanliness level is "1." - Measured "particles," "moisture," and "total oil concentration" in the air discharged from air guns in a supplier's factory that supplies parts to a semiconductor manufacturer. Demonstrated that the cleanliness level of particles and oil in the discharged air is "0." - Conducted microbiological testing on the compressed air used in the production facility of a bottled water manufacturer. Reported that no bacteria are present in the compressed air (CFU/m³ < 1).
