Product Announcement from Saint-Gobain Surface Conditioning Group
Saint-Gobain's 92400.20MIC12 Polycrystalline Alumina Slurry for C plane sapphire wafer polishing is a truly remarkable product. It replaces colloidal silica, SiO2, the traditional final polishing slurry used for many years on C plane sapphire wafers. This slurry can polish the sapphire wafers 2 - 3 times faster than colloidal SiO2, and it doesn't scratch the sapphire wafers, is much more easily cleaned from the wafers and the polishing machinery.
