Sic wafer polishing
WebThe results indicated that the Fe and Al2O3-impregnated pads can be effectively used for SiC wafer polishing. When the proposed process was employed for polishing single-crystal SiC, both the polishing time and cost were reduced. This novel design can facilitate the extensive use of single-crystal SiC wafers in the future. WebWorld Leader in SiC Single-Wafer Processing Equipment.
