In the core equipment of semiconductor chip manufacturing (such as lithography machines, wafer handling robotic arms, and vacuum etching machines), semiconductor clean bearings play an absolutely core role in ensuring nanometer-level precision positioning and an absolutely clean environment. Chip manufacturing is the pinnacle of human precision manufacturing; any minute particle contamination, lubricant evaporation, or magnetic field interference can lead to the scrapping of an entire wafer. Traditional bearings in vacuum or high-cleanliness environments are highly susceptible to generating particles due to grease evaporation or producing dust from metal friction, becoming an "invisible killer" of yield rates. Semiconductor equipment manufacturers urgently need support bearings customized for cleanrooms and vacuum environments, featuring ultimate zero-contamination and ultra-high-precision characteristics.

Facing the stringent semiconductor manufacturing requirements for "absolute cleanliness" and "nanometer-level precision," support systems must not only possess ultra-low friction and extremely high dimensional stability but also achieve absolute zero-evaporation and non-magnetic properties in ultra-high vacuum and strong magnetic field environments. Due to material and lubrication system limitations, traditional bearings are highly susceptible to cold welding and lubrication failure in vacuum environments, causing wafer handling robotic arms to jam. Furthermore, ordinary seals are prone to generating micro-dust during long-term operation, directly contaminating the expensive process environment. The market urgently demands a semiconductor clean bearing solution that can break through the dual bottlenecks of vacuum cold welding and particle contamination, maximizing wafer yield, providing solid protection for chip intelligent manufacturing.

NMT Semiconductor Clean Bearings are born to conquer the ultimate cleanliness challenges of chip manufacturing. This series achieves disruptive breakthroughs in materials and structures by comprehensively using non-magnetic special alloys and high-purity ceramic materials, completely eliminating magnetic field interference and dust shedding. In terms of lubrication, NMT uses aerospace-grade perfluoropolyether (PFPE) vacuum-specific grease with extremely low TVOC (total volatile organic compounds) content, achieving true "zero evaporation" under ultra-high vacuum conditions of 10⁻⁷ Pa. Meanwhile, through special surface passivation and atomic-level polishing processes, it ensures that the bearings do not generate any micro-dust during long-term high-frequency operation, perfectly adapting to the nanometer-level precision positioning of wafer handling robotic arms.

In precision manufacturing and quality control, NMT enforces cleanroom-grade stringent standards for every component of its semiconductor clean bearings. Through special clean material selection, vacuum lubrication optimization, and ultra-precision assembly processes, the cleanliness and reliability of the bearings are comprehensively improved. NMT ensures that each bearing can effectively resist the erosion of vacuum environments and strong magnetic fields, avoiding cold welding, evaporation, and particle contamination, guaranteeing high consistency and high reliability of batch products, and completely eliminating yield hazards in semiconductor production lines.

With rich specifications, these bearings are widely used in wafer handling robotic arms, lithography machine workpiece stages, vacuum etching and deposition equipment, semiconductor testing and packaging equipment, and cleanroom automated transport systems, satisfying the supporting needs of various ultra-high-precision, zero-contamination, vacuum-resistant, and non-magnetic transmission nodes.
