Abstract
A semiconductor structure and method of manufacturing the same are provided. The semiconductor device includes an enhanced performance electrical fuse formed in a polysilicon fin using a trench silicide process. In one embodiment, at least one semiconductor fin is formed on a dielectric layer present on the surface of a semiconductor substrate. An isolation layer may be formed over the exposed portions of the dielectric layer and the at least one semiconductor fin. At least two contact vias may be formed through the isolation layer to expose the top surface of the semiconductor fin. A continuous silicide may be formed on and substantially below the exposed surfaces of the semiconductor fin extending laterally at least between the at least two contact vias to form an electronic fuse (eFuse). In another embodiment, the at least one semiconductor fin may be subjected to ion implantation to facilitate the formation of silicide.
