    摘要: An electronic fuse for an integrated circuit and a method of fabrication thereof are presented. The electronic fuse has a first terminal portion and a second terminal portion interconnected by a fuse element. The fuse element has a convex upper surface and a lower surface with a radius of curvature at a smallest surface area of curvature less than or equal to 100 nanometers. Fabricating the electronic fuse includes forming an at least partially freestanding dielectric spacer above a supporting structure, and then conformably forming the fuse element of the fuse over at least a portion of the freestanding dielectric spacer, with the fuse element characterized as noted above. The dielectric spacer may remain in place as a thermally insulating layer underneath the fuse element, or may be removed to form a void underneath the fuse element.

    摘要: Systems and methods for controlling electro-migration, and reducing the deleterious effects thereof, are disclosed. Embodiments provide for reversal of an applied voltage to an integrated circuit when a measurement indicative of an extent of electro-migration indicates that a healing cycle of operation is warranted. During the healing cycle, circuits of the integrated circuit function normally, but electro-migration effects are reversed. In one embodiment, micro-electro-mechanical switches are provided at a lowest level of metallization to switch the direction of current through the levels of metallization of the integrated circuit. In another embodiment, if the measurement indicative of the extent of electro-migration exceeds a reference level by a specifiable amount, then the voltage applied to the integrated circuit is reversed in polarity to cause current to switch directions to counter electro-migration. A plurality of switches are provided to switch current directions through a lowest level of metallization so that the circuits function normally even though the polarity of the applied voltage has been reversed.
