Webour knowledge of SiC grinding, prime wafer polishing, and CMP technology to develop a unique solution that truly makes polishing SiC easy. We are pleased to introduce you to the 6EZ, the world’s first fully-automated, single wafer, dry-in-dry-out polisher designed specifically for SiC. The 6EZ makes SiC polish EZ! • Fully-automated, Webon the polishing of SiC wafers in preparation for further processing (e.g. epitaxial growth and device fabrication). Polished SiC wafers should demonstrate a flat surface over the wafer-scale area, limited waviness and roughness, a scratch-free morphology, and the absence of a sub-surface damaged layer. Under macro-defects, we include polytype
