In practical production, a sapphire waffle is made by cutting a crystal rod, followed by grinding and polishing. Generally, a semiconductor wafer is cut into wafer by wire cutting or multi-wire cutting machine. Since the cutting conditions always change during the cutting process, there are variations in the thickness and flatness of the cut ...

This paper reports our recent results on the diamond grinding process of single crystallized sapphire wafers. It was found that the diamond grains were severely dislodged at the wheel/ workpiece interface and the material was removed by a mixed process of both grinding and lapping. Grinding governed the wafer center while lapping dominated its fringe.
