Designable channel finfet fuse

A monolithic structure, comprising:

• a substrate including a plurality of parallel, monocrystalline semiconductor fins, the fins including one or more channel regions and outer fin portions integral with and adjoining the channel regions;
• source/drain regions on the outer fin portions of one or more of the fins, each of the channel regions being adjoined by a pair of the source/drain regions;
• and
• a gate structure adjoining each channel region;
• wherein the channel region of at least one of the parallel semiconductor fins includes a substantially polycrystalline, doped fuse region operatively associated with a pair of the source/drain regions.
