Principles of Ferrofluid Feedthroughs for Semiconductor Manufacturing Equipment
In semiconductor manufacturing, producing high-quality products relies on ferrofluid feedthroughs.
Ferrofluid feedthroughs completely isolate the internal cavity from the external environment, maintaining a stable manufacturing environment.
The ferrofluid feedthroughs introduced in this article use a magnetic fluid sealing mechanism. Magnetic fluid is a liquid that is attracted by magnets. By clamping magnetic fluid with magnets, the gap between the rotating shaft and fixed components is effectively sealed, isolating the interior from the exterior.
Ferrofluid feedthroughs are non-contact, so friction and wear are minimal, ensuring a long service life. In addition, they can adapt to high-speed rotation and are suitable for various semiconductor manufacturing equipment. By adjusting the viscosity of the magnetic fluid, different pressure conditions can be handled, providing flexibility.
Ferrofluid feedthroughs have been integrated into various semiconductor manufacturing equipment, and their high sealing performance significantly contributes to high-quality semiconductor production.
Applications of Ferrofluid Feedthroughs in Semiconductor Manufacturing
Semiconductor manufacturing requires extremely high process precision, and equipment must maintain a vacuum state to prevent contamination. Ferrofluid feedthroughs play a key role in maintaining the vacuum. The following describes specific applications from process, peripheral equipment, and component perspectives:
· Role in processes such as CVD, PVD, and etching
· Role in peripheral equipment such as wafer handling and inspection devices
· Sealing connections of vacuum chambers and pipelines
Role in CVD, PVD, Etching, and Other Processes
In semiconductor processes, ferrofluid feedthroughs play a critical role at every stage. In CVD, to form uniform films on wafers, ferrofluid feedthroughs enable wafer rotation in the process chamber.
In PVD, when materials evaporate and deposit films in the chamber, ferrofluid feedthroughs maintain chamber vacuum.
During etching with plasma or chemicals to remove unwanted parts, ferrofluid feedthroughs are used on wafer-handling robots to prevent impurities from entering the chamber.
Ferrofluid feedthroughs are also used in ion implantation equipment, vacuum heat treatment furnaces, single-crystal pulling devices, and inspection equipment. Clearly, ferrofluid feedthroughs are indispensable in every semiconductor manufacturing process and critical for high-quality production.
Role in Wafer Handling and Inspection Equipment
In wafer handling and inspection, ferrofluid feedthroughs ensure a high-precision, clean environment, preventing external contamination and maintaining stable process conditions.
In particular, vacuum robots used to transport wafers inside chambers rely on ferrofluid feedthroughs at joint parts to prevent dust intrusion, minimizing wafer contamination risk and improving yield.
Vacuum suction cups for wafer holding also use ferrofluid feedthroughs, ensuring wafers remain secure without damage, maintaining stability in handling and inspection.
Vacuum Chamber Sealing
In semiconductor manufacturing, vacuum chambers directly affect process purity and efficiency. Contamination or leakage can reduce vacuum levels and impact yield. Therefore, connection points require high sealing performance.
Selecting sealing materials requires considering vacuum level, temperature, gas environment, and cost. Choosing the appropriate sealing material improves process stability and yield.
Ferrofluid Feedthrough Selection Methods
The material and shape of ferrofluid feedthroughs vary depending on manufacturing process type and conditions. Selection should consider:
First, clarify the usage environment, including chamber pressure, temperature range, and chemical resistance. Then, consider the shape, size, and required sealing performance of the components to be sealed. Additionally, flange or joint type affects the selection.
By choosing the appropriate sealing material and flange combination, high sealing performance is ensured. Comparing the characteristics of common sealing materials allows selection of the most suitable product.
Future Demand and Development of Ferrofluid Feedthroughs
As semiconductor manufacturing equipment evolves, the requirements for ferrofluid feedthroughs continue to increase.
With finer processes, the need for clean environments rises, and controlling particle generation becomes a key issue. To meet these needs, ferrofluid feedthroughs using low vapor pressure fluorinated oil have become mainstream.
High-temperature adaptability is also a focus of future development. For example, in high-temperature CVD processes, high-heat-resistance magnetic fluids are being developed to maintain stable sealing performance.
Meanwhile, the application of ferrofluid feedthroughs is expanding beyond semiconductors. Medical equipment, analytical instruments, and other fields requiring vacuum environments also need high-performance ferrofluid feedthroughs. Clearly, ferrofluid feedthroughs will play a key role in future technological innovations.
