NettetN: A scaling factor that usually ranges between 1 and 2 to quantify the contributions diffusion processes to electromigration (see above). k: Boltzmann’s constant, or … NettetAt the same time, the dimensions of the minimum size wires (i.e., used for local wiring) decreases. Hence, ideally, a higher current density is required in the wires ( Figure 8.19 …
Nettet9. feb. 2024 · With the increasing number of inputs and outputs, and the decreasing interconnection spacing, electrical interconnection failures caused by electromigration (EM) have attracted more and more attention. The electromigration reliability and failure mechanism of complex components were studied in this paper. The failure mechanism … Nettet12. apr. 2024 · With the reduction of contact area, the current density flowing in a microbump becomes much larger than that in a conventional FC bump. For a 20 µ m microbump applied by 0.2 A, the current density...
NettetAs shown by Blech, prevention of electromigration damage is possible when the product of the current density, j, and line length, l, is below a critical value (as shown below): ( j … Nettet24. mar. 2013 · The intention is to increase current density limits in the interconnect by adopting electromigration-inhibiting measures, such as short-length and reservoir effects. Exploitation of these effects at the layout stage can provide partial relief of EM concerns in IC design flows in future.
NettetLN, of the one or more conductive segments formed at the one or more additional widths is selected such that, for a given magnitude of current carried by the conductive line, a critical length with respect to an electromigration short-length effect benefit is maintained such that a total length of the conductive line, L=L1+L2+ . . . +LN, meets a minimum desired …
