Abstract
In a semiconductor device having a fusewhich makes connection between a first interconnectionand a second interconnection, and a first low heat-conductive sectionwhich makes connection between the first interconnectionand a third interconnectionat a site of the first interconnectionwhere the fuseis not connected, the first low heat-conductive sectionis fabricated from a material having a heat conductivity lower than that of the material to form the first interconnection. When the fuse is blown with the laser beam irradiation, the heat dissipation through the heat conduction along the fuse and the interconnection is to be suppressed, and thereby a satisfactory disconnection at the fuse is to be achieved.
