What is the compressed air quality standard for the semiconductor industry?

Compressed air quality standards for the semiconductor industry usually include a number of indicators, such as particulate matter, humidity, oil content, microbiological and chemical pollutants. The specific values of these standards may vary depending on the production process and application requirements.

Particulate matter: The particulate matter in the semiconductor compressed air must be very small, and the particulate matter concentration is usually less than 100 per cubic foot (or less) to ensure the cleanliness of the production environment and the quality of the product.

Humidity: The humidity in the semiconductor compressed air must be controlled to prevent the product from being affected by humidity. A relative humidity of less than 50% is usually required to prevent the product from being affected by moisture.

Oil content: The oil content in the semiconductor compressed air must be very low, usually the total oil content is less than 1ppm to ensure the quality of the product and the stability of the production process.

For the control of microbial and chemical contaminants, strict standards are also required, but the specific values may vary depending on the production process and requirements. In order to ensure the quality of semiconductor products and the stability of production, it is necessary to strictly control the quality of semiconductor compressed air, comply with relevant standards and take effective purification measures.

Please note that the above standards are not fixed and may be adjusted as technology advances and industrial needs change. Therefore, in practical application, reference should be made to the latest industry standards and specifications.
