Edge chipping of silicon wafers in diamond grinding

2013-1-1 · 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 (down-grinding mode).

Silicon wafer downsizing Sil'tronix Silicon Technologies

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 is fitted.
