Abstract
In some aspects of the invention, a first polysilicon fuse section for forming a cavity is provided in close proximity to a second polysilicon fuse section for adjusting circuit characteristics. By forming a cavity with the first polysilicon fuse section made to be blown, fused polysilicon is contained in the cavity when the second polysilicon fuse section is blown to make it possible to provide a polysilicon fuse capable of stably maintaining an electrical insulated state. This can provide a polysilicon fuse capable of stably maintaining the electrical insulated state when the fuse is blown, a semiconductor device having the polysilicon fuse and a method of severing the polysilicon fuse.
