CM-S700主要由高純度膠態(tài)二氧化硅組成,特別適用于2-6寸GaAs晶片的拋光,具有穩(wěn)定性和分散性良好,去除率高、表面粗糙度小以及對工件無損傷等優(yōu)點。即使在稀釋倍率很高的情況下使用,仍具有很好的拋光效率和使用壽命。
CM-S700 is a colloidal silica slurry developed especially for polishing 2-6 inches GaAs wafer, with excellent particle stability and dispersal, it possesses a high removal rate, good surface effects and damage-free polishing. Even when used at high dilutions, CM-S700 delivers excellent processing efficiency and long slurry life.
