Claim:
1. A semiconductor device, comprising: a substrate; an insulating layer formed over the substrate; a first conductive plate formed in the insulating layer and formed at a first wiring layer; a fuse element formed in the insulating layer and formed at a second wiring layer, the second wiring layer being one level above the first wiring layer; and a second conductive plate formed in the insulating layer and formed at a third wiring layer, the third wiring layer being one level above the second wiring layer; wherein the fuse element includes copper, wherein the fuse element is brought into a blow state by a current supplied thereto, wherein the fuse element has a first portion including a meltdown portion and a second portion that is wider than the first portion, wherein the first portion is bent a plurality of times, wherein the first conductive plate is formed below the fuse element in a planar view, and wherein the second conductive plate is formed above the fuse element in the planar view.
