In wafer manufacturing, compressed air plays a vital role, and its role runs through many key process links, as follows:
in the lithography machine, the compressed air drives the air cylinder and the pneumatic motor to realize the fast and accurate movement of the shutter control mechanism, the lens positioning and adjustment device and other precision mechanical parts. This stable power output ensures that the lithography machine is positioned accurately in the lithography operation with nano-scale precision, thus ensuring the precision of the chip pattern transfer.
during the etching process, compressed air is used to drive the valves of the gas delivery system to precisely control the flow and pressure of the etching gas. This precise control ensures the etching rate and uniformity, so that a specific area of the wafer can be precisely etched to form a complex chip structure.
in a chemical vapor deposition (CVD) apparatus, compressed air drives a uniform distribution of reactant gases within a reaction chamber. This uniform distribution provides stable process conditions for depositing high-quality thin films on the wafer surface, which helps to improve the performance and reliability of the chip.
automated robotic arms in fabs extensively use compressed air as a power source to achieve rapid grasping, handling and precise positioning of wafers, carriers and other materials. The pneumatic gripper of the mechanical arm realizes the grasping and releasing action of the object through the inflation and deflation of the compressed air. Its fast response and precise control capabilities meet the needs of fabs for efficient production.
in the orbital material transfer system, compressed air drives the transfer carrier to run on the track, and the wafer is quickly and smoothly transported from one processing station to the next. This transmission method improves production efficiency, reduces manual intervention, and reduces the risk of wafer contamination.
in all aspects of wafer processing, tiny particle contaminants can affect chip performance and yield. The compressed air, which has been strictly filtered and dried, purges the wafer surface with high-speed air flow through a special air nozzle or spray gun to effectively remove dust, debris and other impurities and ensure the cleanliness of the wafer surface.
regularly using compressed air to purge the interior of the production equipment can remove dust, powder and other pollutants accumulated during the operation of the equipment. This cleaning method prevents the adverse effects of impurities on the performance and stability of the equipment, and prolongs the service life of the equipment.
in order to prevent external contaminants from entering the clean production area, the clean room of the wafer fab usually uses a positive pressure ventilation system. Compressed air is delivered to the clean room, so that the indoor pressure is higher than the external environment, forming an air barrier. This barrier prevents the intrusion of dust, microorganisms and other pollutants, and maintains a high standard clean environment in a clean room.
In pharmaceutical factories, according to production requirements, process characteristics and air quality requirements, the following types of air compressors are usually selected: oil-free air compressors: due to the high air quality requirements of pharmaceutical production, oil-free air compressors can provide pure and oil-free air compressors.
The main difference between oil and oil-free air compressor is reflected in the following aspects: material difference: oil air compressor: its own material contains oily substances, which may cause pollution to the terminal equipment connected to it. Oil-free air compressor: its body material is not
There may be many reasons for the loud noise of the screw air compressor. The following are some common reasons: Motor noise: When the motor is running, it will produce mechanical noise, electromagnetic noise and ventilation noise. Among them, ventilation noise is usually larger, followed by mechanical noise, electromagnetic noise phase
In the semiconductor factory, the air compressor plays a vital role. The following is the detailed application of air compressors in semiconductor factories: 1. provide a stable gas source. The semiconductor production process has very strict requirements on the purity, humidity, and pressure of the gas. Air compressor capacity
The screw air compressor will not stop all the time. It will also need rest and maintenance after working for a period of time like other machines. Although the screw air compressor has high stability and durability, long-term continuous operation may also cause the equipment to overheat,
There is no fixed standard for the running time of the explosion-proof air compressor, because it is affected by many factors, including the design of the air compressor, the use of the environment, the load situation, the maintenance condition, etc. However, in general, high-quality explosion-proof air compressor in the design
When discussing whether the gas transmission and displacement of the compressor are the same, we first need to clarify the definition and measurement of these two concepts. Gas delivery, usually refers to the compressor in a unit of time to the system or equipment delivery
Advantages of dry oil-free air compressor products: 1. The motor adopts advanced design system to optimize the design to ensure that the compressor achieves high power, high efficiency, low energy consumption, high performance and high reliability. 2. The piston ring adopts new environmental protection material design, friction system
The semiconductor industry has very strict requirements for compressed air, because compressed air is directly in contact with the product, and its quality and purity directly affect the quality and performance of the product. The following are the main requirements for compressed air in the semiconductor industry: Particle control: due to semi-conductivity
The compressed air of the fermentation tank mainly comes from the air compressor. These compressors provide the fermenter with the required compressed air through a specific system. The following is a detailed explanation about the source of compressed air in the fermentation tank: The role of the air compressor: air
