With the continuous development of science and technology, semiconductor manufacturing technology is changing with each passing day, and the requirements for various materials are getting higher and higher. As a new type of material, silicon nitride ceramic balls play a special role in semiconductor manufacturing. Silicon nitride ceramic ball is a high-purity, high-density, high-hardness ceramic material, with excellent high temperature resistance, corrosion resistance, wear resistance. Compared with traditional glass beads, silicon nitride ceramic balls have higher hardness and impact resistance, and are able to withstand higher temperatures and pressures. In addition, silicon nitride ceramic balls have good chemical stability and are not easy to react with acids, alkalis and other substances, ensuring their stability and reliability in semiconductor manufacturing.
In semiconductor manufacturing, silicon nitride ceramic balls are mainly used in polishing and grinding. First of all, in the polishing process, silicon nitride ceramic balls can effectively remove the roughness and scratches on the surface of the silicon wafer and improve the surface finish and flatness of the silicon wafer due to its high hardness and wear resistance. Secondly, in the grinding process, silicon nitride ceramic balls can effectively reduce the roughness of the surface of the silicon wafer and make it meet the requirements of higher flatness.
