Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a semiconductor wafer having a substrate including a front surface, an interlayer insulating film formed on the front surface of the substrate, a first chip region formed over the front surface of the substrate, a second chip region formed over the front surface of the substrate and arranged next to the first chip region, a cutting region formed over the front surface of the substrate and formed between the first chip region and the second chip region in a plan view, a metal pattern formed over the front surface of the substrate and formed in the cutting region in the plan view and arranged between the first chip region and the second chip region in the plan view, and a back surface opposite to the front surface, wherein the interlayer insulating film has a wiring layer and a low-dielectric constant film, wherein the substrate is comprised of a silicon, and wherein the low-dielectric constant film is more brittle than the substrate;
