This equipment is designed for a Φ485mm ceramic disc, performing polishing on wafers attached to it. It is suitable for various wafer substrate materials including 4-8 inch Si, SiC, GaAs, and Ge wafers. The system features four actively driven polishing heads, combined with innovative multi-zone pressure application, precise temperature control, and pressure control systems, enabling highly efficient, high-flatness, and low-scratch polishing. Specifically for ultra-hard third-generation semiconductor materials like SiC, an ultra-high pressure configuration is available, significantly enhancing processing capacity.
