]. In this study, according to basic reaction mechanisms we treated the sapphire substrate by CMP method using a new-type slurry and obtained high removal rate and low roughness. 2 Experimental In this study... jamming, which influences the slurry transmitting. Then it causes chemical reaction to be slower, removal rate to decrease and surface quality to be lower. According to our experiment results, the pH......
