<p>PROBLEM TO BE SOLVED: To actually prevent occurrence of a crack when a fuse is burned out in the fuse for semiconductor device having a semiconductor body 1, an insulating layer 2 at least partly provided on the upper face of the semiconduc tor body 1, and an web like metal layer 3. SOLUTION: The web like metal layer 3 is arranged on the layer 2, and the layer 3 has narrow area 4 to form the fuse on at least is one area. The prescribed semiconductor area 6 in the semiconductor body 1 is made under the narrowed area 4 with porous semiconductor material so as to insulate the heat.</p> |
