Why does the semiconductor industry have to use absolute class 0 oil-free air compressors?
How does the high-end semiconductor manufacturing industry choose a pure oil free air compressor? A semiconductor (semiconductor) refers to a material whose electrical conductivity is between that of a conductor and an insulator at room temperature. Semiconductors are widely used in integrated circuits, computers, consumer electronics, communication systems, photovoltaic power generation, lighting applications, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is the most influential one in commercial applications among various semiconductor materials.
The production of semiconductors and chips is inseparable from compressed air. In this process, the air compressor provides air power for the production of machine tools, pneumatic valve equipment, and purging. Most of the compressed air is used for product purging and other links. . Since a large amount of waste and debris are generated during the production process, compressed air is required to purge and clean fine circuit components such as circuit boards, so as to proceed to the next production link. Therefore, the semiconductor industry and the chip industry have almost strict requirements on the quality of compressed air, and oil-free air compressors have become the standard for precision industries such as semiconductors.
1. Application of compressed air in semiconductor and electronic factories
Cooling Air: Product cooling in clean rooms is a critical clean air application in electronics factories.
Cleanroom: The cleanroom is the heart of the plant. In addition to controlling the temperature and humidity in the clean room, all dust or other contaminants must be avoided. This means that the compressed air must be class 0 oil-free air to avoid any contamination.
Etching and Deposition: Etching and deposition is the process of imprinting a specific pattern on a wafer.
Instrumentation and Pneumatic Tools: Compressed air is used in instrumentation or pneumatic applications such as sorting, packaging, testing, handling, assembly, etching, etc. Using oil-free air ensures that your products are not contaminated during production.
Purification: To avoid contamination, oil-free air purification is recommended.
Wastewater Treatment: Wastewater from manufacturing must be treated before being released into the natural environment. More about wastewater treatment
Soldering: Soldering electronic components with high-quality nitrogen (that is, high-purity nitrogen) has several advantages. This not only improves product performance, but also brings environmental benefits.
It can be seen that clean and dry compressed air is very important for semiconductor factories, and any problems with air quality can have catastrophic consequences, so it is very important to have a reliable compressed air supplier.
2. How to choose oil-free air compressors in the semiconductor industry
What are the standards and references for the semiconductor industry and manufacturers to choose oil-free air compressors?
1. You can choose air compressor equipment with high energy efficiency level according to your own working conditions. If the gas consumption fluctuates greatly, you can choose a variable frequency oil-free air compressor.
2. According to the production situation of the semiconductor factory, 37KW and 75KW oil-free air compressor 0.8mpa models are widely used in the semiconductor industry, and the specific equipment selection can be tailored according to the working conditions.
3. The cleanliness of the air. When choosing an air compressor, most manufacturers will choose a food-grade aseptic oil-free air compressor, which ensures the quality rate of the processed products and prevents the use of compressed air containing impurities in the production process. the possibility of secondary pollution.
4. It is necessary to ensure continuous gas supply, so as to avoid downtime and affect product quality, and ensure the stable operation of gas-using equipment.
The above is to introduce the characteristics and requirements of the oil-free air compressor selection in the semiconductor industry.
With the blockade of high-tech technology and equipment in China by the United States in recent years, such as those used in the semiconductor and chip industries: ShinEtsu in Japan, Dow in the United States, Advanced Semiconductor Material Lithography, etc. With advanced technology and equipment, it is the general trend to realize the gradual localization of the semiconductor and chip industries.
A Shanghai Semiconductor Co., Ltd. is mainly engaged in semiconductor technology, optoelectronic technology, crystal technology, etc. The main semiconductor is silicon wafers. The company's research and development equipment needs to use compressed air. After the business personnel of Zhuoying Machinery (Shanghai) Co., Ltd. understand the needs, they will come to the door to formulate the air plan for oil-free screw air compressors for free, and recommend Zhuoying JMW-55APM oil-free water lubrication permanent magnet frequency conversion according to the needs. Screw air compressors and supporting solutions. After many rounds of screening and comparison, the customer company finally adopted the oil-free air compressor system solution recommended by Zhuoying Machinery.
3. Features of Zhuoying Machinery's oil-free air compressor
1. Structure without lubricating oil: no oil is involved in all systems of the oil-free screw air compressor. The lubricant used is pure water filtered through layers, so it can provide clean compressed air.
2. Ideal isothermal compression: Since the cooling performance of water is much higher than that of air compressor oil, the operating temperature of the oil-free screw air compressor is only 40-50 °C, which is close to the suction temperature and achieves high-efficiency ideal isothermal compression. . High efficiency, and very easy to avoid high temperature shutdown, which is especially important for critical industries.
3. The real environmental protection efficiency is high: because there is no lubricating oil, there is no oil pollution, ensuring the clean and hygienic production site; the high-precision water filter ensures that the lubricating water maintains clean water quality. The pure water used by the oil-free air compressor has three functions of sealing, cooling and lubrication, and the gas production per unit horsepower is 20% higher than that of the general dry compressor.
4. The inverter series air compressor saves energy by 35% compared with ordinary air compressors, and saves energy by more than 15% compared with dry oil-free air compressors.
5. The equipment adopts a single-screw stainless steel main engine, which has good dynamic balance, stable operation, low noise, and simple maintenance in the later period.
6. The routine maintenance cost is significantly lower than that of the micro-oil screw machine.
