Abstract: 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.

Abstract: A fuse includes a fuse portion laid in such a manner that the direction of each turn of the fuse portion is parallel to the direction in which pads are arranged. The distance between the pads and the fuse portion is defined as the distance between the side of a pad facing the fuse portion and the pad nearest to the turn facing the particular side. The distance between the turn of the fuse portion and the nearest pad is the distance between the pads and the fuse portion. The pads and the fuse portion are distant from each other by a length at least ten times the width of the fuse.

Abstract: On a semiconductor substrate a silicon oxide film is formed and provided with a recess. In the recess a reflector layer of copper is disposed as a blocking layer with a barrier metal posed therebetween. The reflector layer of copper is covered with a silicon oxide film and thereon a fuse region provided with a plurality of fuses is provided. The reflector layer of copper has a plane of reflection recessed downward to reflect a laser beam. The reflector layer of copper is arranged to overlap substantially the entirety of the fuse region, as seen in a plane. A laser beam radiated to blow the fuse can have a reduced effect on a vicinity of the fuse region. A semiconductor device reduced in size can be obtained.
