摘要： Provided is a semiconductor device having an electric fuse structure which receives the supply of an electric current to be permitted to be cut without damaging portions around the fuse. An electric fuse is electrically connected between an electronic circuit and a redundant circuit as a spare of the electronic circuit. After these circuits are sealed with a resin, the fuse can be cut by receiving the supply of an electric current from the outside. The electric fuse is formed in a fine layer, and is made of a main wiring and a barrier film. The linear expansion coefficient of each of the main wiring and the barrier film is larger than that of each of the insulator layers. The melting point of each of the main wiring and the barrier film is lower than that of each of the insulator layers.

摘要： A semiconductor device is provided which includes an interlayer dielectric formed on a semiconductor substrate, a first insulating layer, having a trench, formed on the interlayer dielectric, a barrier film formed on side and bottom surfaces of the first trench, an electric fuse formed on the barrier film, a second insulating layer formed to directly contact the electric fuse, and a third insulating layer formed on the second insulating layer. A linear expansion coefficient of the electric fuse is greater than a linear expansion coefficient of the first insulating layer and the second insulating layer, and a melting point of the barrier film is greater than a melting point of the electric fuse.
