1. Core Industry Pain Points of Semiconductor Equipment Bearings

As semiconductor chip processes iterate toward advanced 5nm, 3nm and below nodes, wafer manufacturing equipment imposes extremely strict requirements on bearing cleanliness, precision stability and environmental adaptability. The entire wafer processing is carried out in high-vacuum and dust-free clean workshops. Lubricant volatilization and particle shedding from ordinary industrial bearings directly cause wafer surface defects and circuit short circuits, leading to massive wafer scrapping.

Core transmission mechanisms of lithography and etching machines require long-term micro-feeding and high-frequency reciprocating operation. Bearings are prone to micro-wear and precision drift. Tiny vibrations amplify lithography deviation and uneven etching, severely affecting chip yield rate. In vacuum enclosed environments, ordinary lubricants easily dry up and fail, causing bearing jamming and abnormal torque and resulting in equipment shutdown. High-end ultra-precision clean bearings for semiconductor equipment have long relied on imports with high prices and long lead times, restricting the industrialization of domestic semiconductor equipment.
