Abstract:
1. A semiconductor device, comprising: a semiconductor substrate; a copper fuse; a plurality of insulating layers, each of the plurality of insulating layers having a first via hole and a second via hole, the first via hole and the second via hole being filled with a first conductive material and a second conductive material, respectively, wherein one of the plurality of insulating layers is formed on an upper layer of the copper fuse; a wiring layer formed on each of the plurality of insulating layers, the wiring layer having a first contact portion and a second contact portion that are connected to the first conductive material and the second conductive material, respectively, the wiring layer being made of a metallic layer that includes a metallic material other than copper; first and second sealing layers disposed between the semiconductor substrate and the copper fuse, the first and second sealing layers being made of copper, wherein at least one of the plurality of insulating layers is provided between the first and second sealing layers so that the first and second sealing layers are apart from each other; and a copper sealing member coupled to the first and second sealing layers and formed to have a container-like shape that surrounds the copper fuse.
