uses the brittle mode, micro-cracks called chippings are generated on the front and rear sides of the wafer. As a countermeasure for this problem, dicing before grinding (DBG) process is also applied. In this process, as shown in Fig. 2, grooving (half-cut dicing) is performed from the front side before grinding. Then, when the
