Abstract:
1. A method for fabricating a semiconductor device comprising the steps of: (a) forming a first dicing line group including a plurality of first dicing lines by dicing along a first direction of a semiconductor wafer; and (b) forming a second dicing line group including a plurality of second dicing lines by dicing the semiconductor wafer along a second direction perpendicular to the first direction, wherein in the (a) step, dicing starts from an outside of the semiconductor wafer, and after cutting off the semiconductor wafer, dicing is ended outside the semiconductor wafer, and the (b) step includes the steps of: (b1) starting dicing from the outside of the semiconductor wafer, cutting off the semiconductor wafer, and then ending dicing outside the semiconductor wafer; and (b2) starting dicing from the outside of the semiconductor wafer and ending dicing inside the semiconductor wafer.
