    摘要: An electronic structure having wiring, and an associated method of designing the structure, for limiting a temperature gradient in the wiring. The electronic structure includes a substrate having a layer that includes a first and second wire which do not physically touch each other. The first and second wires are adapted to be at an elevated temperature due to Joule heating in relation to electrical current density in the first and second wires. The first wire is electrically and thermally coupled to the second wire by an electrically and thermally conductive structure that exists outside of the layer. The width of the second wire is tailored so as to limit a temperature gradient in the first wire to be below a threshold value that is predetermined to be sufficiently small so as to substantially mitigate adverse effects of electromigration in the first wire.

    摘要: A thermo-mechanical cleavable structure is provided and may be used as a programmable fuse for integrated circuits. As applied to a programmable fuse, the thermo-mechanical cleavable structure includes an electrically conductive cleavable layer adjacent to a thermo-mechanical stressor. As electricity is passed through the cleavable layer, the cleavable layer and the thermo-mechanical stressor are heated and gas evolves from the thermo-mechanical stressor. The gas locally insulates the thermo-mechanical stressor, causing local melting adjacent to the bubbles in the thermo-mechanical stressor and the cleavable structure forming cleaving sites. The melting also interrupts the current flow through the cleavable structure so the cleavable structure cools and contracts. The thermo-mechanical stressor also contracts due to a phase change caused by the evolution of gas therefrom. As the thermo-mechanical cleavable structure cools, the cleaving sites expand causing gaps to be permanently formed therein.

    摘要: A method for determining the electromigration characteristics of a wiring structure in an integrated circuit device is disclosed. In an exemplary embodiment of the invention, the method includes configuring a defined test structure type for the integrated circuit device. The defined test structure type further includes a first line of wiring primarily disposed in a principal plane of a semiconductor substrate, and a second line of wiring connected to the first line of wiring. The second line of wiring is disposed in a secondary plane which is substantially parallel to the principal plane, with the first and second lines of wiring being connected by a via structure therebetween. A thermal coefficient of resistance for the first line of wiring and the via structure is determined, and a wafer-level stress condition is introduced in a first individual test structure of the defined test structure type. Then, at least one parameter value for is determined for the first individual test structure, which parameter value is used to predict a lifetime projection for the wiring structure in the integrated circuit device.

    摘要: Disclosed is a design structure for a semiconductor chip structure that incorporates a localized, on-chip, repair scheme for devices that exhibit performance degradation as a result of negative bias temperature instability (NBTI). The repair scheme utilizes a heating element above each device. The heating element is configured so that it can receive transmission line pulses and, thereby generate enough heat to raise the adjacent device to a temperature sufficient to allow for performance recovery. Specifically, high temperatures (e.g., between approximately 300-400° C. or greater) in the absence of bias can accelerate the recovery process to a matter of seconds as opposed to days or months. The heating element can be activated, for example, on demand, according to a pre-set service schedule, and/or in response to feedback from a device performance monitor.
