Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a semiconductor wafer having a first chip region, a second chip region arranged adjacent to the first chip region in plan view, a dicing region arranged between the first chip region and the second chip region in plan view, and a plurality of metal patterns arranged in a plurality of columns in the dicing region and arranged along an extending direction of the dicing region; and (b) cutting, in the dicing region of the semiconductor wafer, the semiconductor wafer along the extending direction of the dicing region, wherein the metal patterns have a first-column pattern arranged in a column closest to the first chip region and second column patterns arranged in a column further from the first chip region than the first column pattern, wherein a distance between the first chip region and the first column pattern is smaller than a distance between the first column pattern and the second column pattern and is smaller than a distance between the second chip region and the second column pattern, and wherein in the step (b), the first column pattern is not removed, but the second column pattern is removed.
