    摘要: A metal layer is deposited on the patterned semiconductor material layer containing a cathode semiconductor portion, a fuselink semiconductor portion, and an anode semiconductor portion. The metal layer may be patterned so that a middle portion of the fuselink semiconductor portion has a thin metal layer, which upon annealing produces a thinner metal semiconductor alloy portion than surrounding metal semiconductor alloy portion on the fuselink semiconductor portion. Alternatively, a middle portion of the metal semiconductor alloy having a uniform thickness throughout the fuselink may be lithographically patterned and etched to form a thin metal semiconductor alloy portion in the middle of the fuselink, while thick metal semiconductor alloy portions are formed on the end portions of the fuselink. The resulting inventive electrical fuse has interfaces at which a thinner metal semiconductor alloy abuts a thicker metal semiconductor alloy in the fuselink to enhance the divergence of electrical current.

    摘要: An electrical fuse is formed on a semiconductor substrate and a first dielectric layer is formed over the electrical fuse. At least one opening is formed by lithographic methods and a reactive ion etch in the first dielectric layer down to a top surface of the electrical fuse or down to shallow trench isolation. A second dielectric layer is deposited by a non-conformal deposition. Thickness of the second dielectric layer on the sidewalls of the at least one opening increases with height so that at least one cavity encapsulated by the second dielectric layer is formed in the at least one opening. The at least one cavity provides enhanced thermal isolation of the electrical fuse since the cavity provides superior thermal isolation than a dielectric material.

    摘要: A resistive memory device includes a vertical transistor and a variable resistance layer. The vertical transistor includes a gate electrode on a surface of a substrate, a gate insulation layer extending along a sidewall of the gate electrode, and a single crystalline silicon layer on the surface of the substrate adjacent to the gate insulation layer. At least a portion of the single crystalline silicon layer defines a channel region that extends in a direction substantially perpendicular to the surface of the substrate. The variable resistance layer is provided on the single crystalline silicon layer. The variable resistance layer is electrically insulated from the gate electrode. Related devices and fabrication methods are also discussed.
