Semiconductor manufacturing has extremely high requirements for the vacuum environment and process cleanliness. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating wafers, targets, and vacuum chambers. They also require regular oil changes and maintenance, affecting continuous production. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as wafer adsorption, CVD/PVD coating, plasma etching, ion implantation, lithography, and wafer handling.
Challenges Faced by the Industry
The requirements of semiconductor manufacturing for vacuum systems are not just about "pulling a vacuum", but more importantly, ultra-high cleanliness, high ultimate vacuum, stable repeatability, and low vibration. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate wafers, targets, and vacuum chambers, affecting film quality and device yield.
Insufficient Ultimate Vacuum and Pumping Speed
Processes such as etching, coating, and ion implantation have high requirements for ultimate vacuum and pumping speed. Insufficient pumping speed will prolong process time and affect production capacity.
Unstable Continuous Operation
Semiconductor production lines often require 24-hour continuous operation. Pump body overheating or vacuum fluctuations will directly affect etching uniformity and film consistency.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Under working conditions containing process by-products, the oil is prone to deterioration, and downtime for maintenance affects overall production efficiency.
Leynow Semiconductor Technology Industry Solutions
Targeting the actual working conditions of semiconductor manufacturing, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the high cleanliness requirements of semiconductor manufacturing for wafers and vacuum chambers.
Selection Solutions Matched to Semiconductor Processes
Based on the process type, chamber volume, ultimate vacuum requirements, and pumping speed requirements, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For semiconductor production lines operating continuously for 24 hours, the heat dissipation and anti-corrosion structures are optimized to reduce the risks of pump body overheating and by-product deposition, maintain stable vacuum degree output, and ensure the consistency of etching and coating processes.
