The compressed air system in the semiconductor plant is mainly used for several key process steps to ensure the production efficiency and quality of semiconductor products. Specifically, the role of the compressed air system includes the following aspects:
etching process aids: In semiconductor manufacturing, the etching process is a key step in the use of gas chemistry for material removal. The compressed air system can provide a stable auxiliary gas environment to help the substance in the etching process to diffuse efficiently, thereby improving the etching efficiency. This is because the compressed air can maintain a dry and clean gas atmosphere, which is conducive to the etching reaction.
Spray process support: in the semiconductor production process, such as etching, it is necessary to spray reaction gas and polishing liquid into the reaction chamber. These liquids need to be sprayed by compressed air to ensure uniform and efficient liquid delivery. The cleanliness and stability of compressed air are very important for the spray effect, which directly affects the production quality of the product.
Gas delivery: In semiconductor production, it is often necessary to deliver various gases, such as inert gases in the granulation process, oxygen on the wafer surface, etc. The compressed air system can provide a high-pressure conveying carrier, so that the gas can quickly and accurately move to the surface of the product, thereby ensuring the efficiency and stability of production.
Supply process requirements: In some process steps, such as photolithography, it is necessary to uniformly spray photoresist on the surface of the chip. The compressed air system can provide stable and high-pressure gas for the lithography nozzle to ensure that the photoresist is evenly deposited on the surface of the chip to meet the process requirements.
Clean room environment maintenance: semiconductor production requires extremely high cleanliness, and a tiny grain of dust may cause the failure of the entire circuit. Compressed air systems are usually combined with clean room environment maintenance to maintain the cleanliness of the clean room by providing high-quality compressed air to reduce dust and pollutants in the air.
Energy saving and environmental protection: With the advancement of technology, the compressed air system in the semiconductor plant also pays attention to energy saving and environmental protection. For example, the air compressor using frequency conversion technology can adjust the motor speed according to the actual gas demand, reducing energy consumption. At the same time, the heat generated in the compression process is recovered through the waste heat recovery system, which is used to produce hot water or hot air, etc., to achieve zero exhaust of waste heat.
In summary, the compressed air system in the semiconductor plant plays an important role in etching, spraying, gas delivery, supply process requirements and clean room environment maintenance. At the same time, with the continuous development of technology, the compressed air system also pays more and more attention to the improvement of energy saving and environmental protection performance.
There are many reasons behind the configuration of multiple air compressors in the factory, which together ensure the efficiency and stability of the production process. First of all, the production process of a factory often involves multiple links and departments, and the demand for compressed air in each link may vary.
The maintenance time of the air compressor depends on many factors, including the equipment model, the frequency of use, the operating environment and the specific terms of the maintenance contract. Generally speaking, in order to ensure the normal operation of the air compressor and prolong its service life, the manufacturer will recommend that the user follow
Both oil-free air compressors and oil-free air compressors have their unique advantages and disadvantages, and are suitable for different application scenarios. The advantages of the oil air compressor: the lubrication effect is good, which can effectively reduce the wear of mechanical parts and extend the life of the equipment. Good cooling effect, lubricating oil
In Jiangsu, choosing a high-quality oil-free screw air compressor is very important for many enterprises. Among many brands, the water-lubricated screw air compressor produced by Shanghai Granklin Group stands out with its excellent performance and environmental protection characteristics, and has become a large number of enterprises.
Air compressor is a kind of important equipment widely used in various industrial production, but it is also a potentially dangerous equipment. Therefore, safe operation procedures and precautions must be observed when operating air compressor to ensure personal safety and equipment Normal operation. Lower
The power range of water lubricated air compressor is usually 7.5-250KW. This power range can meet application scenarios of different sizes and needs, from small industrial equipment to large production lines, where suitable water-lubricated air compressors can be found. About Hagrid
Ironworks do use air compressors. Air compressors play a vital role in ironmaking plants, mainly used to provide compressed air to drive various equipment and tools to ensure the quality and safety of ironmaking production. Specifically, the application of air compressors in ironmaking plants is mainly
General air compressor pressure is how much depends on its type, specifications and the use of the environment. The following are some common air compressor pressure ranges: Low pressure air compressor: The working pressure is usually between 0.7 and 1.2 MPa (MPa), that is, 7 to 12 bar. Medium pressure
Compressed air is the basic power source of many industrial production lines, driving cylinders, controlling valves, driving spraying and packaging equipment, almost throughout the entire production process. The oil-free air compressor is used more in food, electronics, medicine and other scenes where the cleanliness of the gas source is required because the output gas does not contain oil. Whether the equipment can supply gas continuously and stably, the setting of maintenance cycle is a key issue.
Whether the screw air compressor adopts frequency conversion technology, in fact, it is obvious that it can be seen. First of all, you can observe whether there is a frequency converter on the compressor, because the frequency converter is a key component to realize frequency conversion control. If there is, then your compressor
