sapphire edge grinding

    For ~φ8-inch | Products | DaitronWaferEdgeGrinder- sapphire edge grinding ,Asymmetric grinding of the device wafer prior to BG results in a reduction of wafer breakage or chipping after BG 2-spindle (Max) Simplified chamfering machine with one grinding station Grinds hard-material wafers (sapphire, SiC, GaN, crystal, quartz) with high precision and no chippingStudy on Grinding Processing of Sapphire WaferThis 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.
