Nanodiamond polishing fluids, with their excellent performance, are widely used in semiconductor silicon wafer polishing, computer hard drive substrate polishing, computer head polishing, fiber optic connector polishing, and polishing precision ceramics, artificial crystals, cemented carbide, and gemstones.
Semiconductor silicon wafer polishing: One of the primary functions of the semiconductor industry is chip design. Chips are the core products of semiconductor technology, including integrated circuits and microprocessors. The fundamental material for semiconductor chips is ultra-smooth, large-scale, planarized substrates. Therefore, polishing and lapping are extremely important steps in the semiconductor chip manufacturing process, directly affecting the flatness of the wafer surface.
Computer hard drive substrate polishing: The smoothness of hard drive substrates directly affects storage density and the stability of the head's flying height. By using nanodiamond polishing fluids, the surface roughness of hard drive substrates can be controlled to below 1nm, meeting the requirements of high-density hard drives.
Computer head polishing: The operating conditions of magnetic heads in hard drive systems are extremely demanding, especially as storage density increases, and the head's flying height is further reduced to sub-nanometer levels. Nanodiamond polishing fluid enables precise machining of magnetic head surfaces, reducing surface roughness and improving operational stability.
Fiber optic connector polishing: Fiber optic connectors in optical communications and fiber optic transmission systems require extremely high geometric accuracy and surface quality. Nanodiamond polishing fluid effectively reduces fiber endface roughness, improving signal transmission efficiency, and is used by a wide range of fiber optic communication equipment manufacturers.
