In grinding a silicon wafer by a diamond wheel, the grinding force at the wafer edge can be decomposed into three components: main grinding force (tangential force) F c, feed force (radial force) F f and passive force (axial force) F p, as shown in Fig. 11 (downgrinding mode).
Silicon wafer edge rounding. Silicon is very hard, but brittle material. The sharp edge of sawn wafers fractures readily, producing unacceptable edge chips and particles. This edge is ground with a diamond disk to remove the damage and to eliminate periferical stress. By edge grinding, the final diameter of the wafer .

Silicon Wafer Edge Grinding Wheels, Find Complete Details about Silicon Wafer Edge Grinding Wheels,Grinding Wheels from Grinding Wheels Supplier or .
Silicon wafers after cutting have sharp edges, and they chip easily. The wafer edge is shaped to remove sharp, brittle edges; rounded edges minimize the risk for slipping, too. The edge shaping operation makes the wafer perfectly round (offcut wafers are oval shaped after slicing), the diameter is adjusted, and orientation flat(s) or notch is dimensioned or made.
