Abstract
On the scribe line area formed between a plurality of semiconductor chip areas on a semiconductor wafer, there is provided a chipping preventing portion constituted by a double groove consisting of the first and second grooves. Thus, the entry of chipping into the semiconductor chip area is prevented when dicing the semiconductor wafer along the scribe line area provided between each of the semiconductor chip areas. In this respect, an insulating film may be formed on the surface of the semiconductor wafer on the side of an element forming area.
