Product Specification

How are ceramic bearings used in semiconductor manufacturing
 
Ceramic bearings play a crucial role in semiconductor manufacturing, where precision, cleanliness, and reliability are essential. Here are some ways ceramic bearings are used in semiconductor manufacturing:
 
►Wafer Handling Systems: Ceramic bearings are utilized in wafer handling systems, which involve the precise movement and positioning of silicon wafers throughout the fabrication process. These bearings provide smooth motion, high accuracy, and excellent repeatability, ensuring the wafers are handled without contamination or damage.
►Vacuum Chambers: Semiconductor manufacturing often involves processes conducted in vacuum environments. Ceramic bearings are used in vacuum chambers, where they provide reliable motion control while maintaining the cleanliness and integrity of the vacuum. They withstand the harsh conditions inside the chamber, such as low pressures and high temperatures.
►Precision Stages and Robots: Semiconductor manufacturing equipment relies on precise motion control for tasks like wafer alignment, lithography, and inspection. Ceramic bearings are used in precision stages and robots to achieve accurate and repeatable movements, ensuring the desired positioning and alignment of components during the manufacturing process.
►Cleanroom Environments: Semiconductor manufacturing requires an extremely clean and controlled environment to prevent contamination. Ceramic bearings are preferred in cleanroom applications due to their non-magnetic and non-corrosive properties. They generate minimal particle emissions and are resistant to chemicals, reducing the risk of contamination in sensitive areas.

Non-Magnetic, Cleaniness and Precise Motion Control for Semiconductor Manufacturing
 
If you use 6001 full ceramic bearings in semiconductor manufacturing, you will get :
 
Firstly, Cleanliness: Semiconductor manufacturing requires an extremely clean and controlled environment to prevent contamination, as even tiny particles can adversely affect the performance and yield of semiconductor devices. Ceramic bearings generate minimal particle emissions, reducing the risk of introducing contaminants into the manufacturing process. They also have low lubricant requirements, minimizing the potential for lubricant-related contamination.
Secondly, Chemical Resistance: Ceramic bearings are highly resistant to chemicals, acids, and corrosive substances commonly used in semiconductor manufacturing processes. They can withstand exposure to various cleaning agents, etchants, and other chemicals without degradation, ensuring their reliability and longevity in such environments.
Thirdly, Non-Magnetic Properties: Magnetic particles or components can interfere with sensitive semiconductor manufacturing processes. Ceramic bearings are non-magnetic, which is crucial in applications where magnetic fields must be controlled or eliminated to prevent disturbances or damage to delicate electronic components.
Fourthly, High Hardness and Wear Resistance: Ceramic materials used in bearings, such as silicon nitride (Si3N4), Silicon Carbide (SSiC) or zirconia (ZrO2), have excellent hardness and wear resistance properties. They can withstand abrasive forces and resist wear, even in demanding operating conditions. This makes ceramic bearings more durable and extends their lifespan, reducing maintenance requirements and downtime in semiconductor manufacturing equipment.
