Applications of Compressed Air in Integrated Circuits

Pneumatic Control and Automation Equipment Drive

In integrated circuit production lines, highly automated equipment is central. Compressed air serves as…Clean, dry airIt is widely used as a power source for pneumatic components. It drives various pneumatic valves, cylinders, and robotic arms, ensuring precise handling and positioning of wafers at every stage of the process. Thanks to its rapid response and smooth motion, compressed air effectively maintains consistent production cycle times and enhances equipment operational efficiency.

Cleanroom Environmental Maintenance and Contamination Control

Integrated circuit manufacturing must be carried out in ultra‑cleanrooms meeting extremely stringent cleanliness standards. Compressed air systems help maintain the indoor environment by continuously supplying rigorously filtered air to these cleanrooms.Slightly positive pressure stateThis positive-pressure environment effectively prevents unfiltered external air and particulates from entering the production area. Furthermore, during equipment maintenance or localized modifications, compressed air is also used for temporary isolation and airflow management to prevent cross-contamination.

Wafer Surface Purging and Drying Process

After wet cleaning and chemical mechanical polishing processes on wafers, residual liquids or minute particles remain on the surface. High-pressure, ultra‑clean compressed air is used to…Surface Purging, to remove adhered particulates. Meanwhile, in certain drying processes, compressed air used in conjunction with other media can accelerate the evaporation and removal of surface moisture from wafers, thereby preventing water‑spot residues from adversely affecting subsequent lithography or etching steps.

Instrument and Meter Air and Process Auxiliary Services

Semiconductor factories house a large number of precision measuring instruments and analytical devices. Compressed air provides these instruments and meters with stable…Power air sourceand protective gases, ensuring the accuracy of measurement data. In certain non‑critical process‑supporting operations—such as internal equipment cooling, actuation of pneumatic tools, and purging and pressure testing of piping systems—compressed air likewise plays an irreplaceable role.

Quality Standards for Compressed Air

Because integrated circuits are extremely sensitive to particulates and moisture, the compressed air used in production lines must meet stringent quality standards. Typically, multi-stage filtration systems are required to remove oil, moisture, and micron‑scale particles from the air. The air’s…Pressure dew pointIt must be maintained at an extremely low level to prevent condensation inside pipelines or equipment. Oil-free compression technology and high-efficiency drying equipment are essential components for ensuring the safety of integrated circuit manufacturing.
