Length electromigration
Nettet13. jun. 2013 · The short-length effect, whereby electromigration is eliminated due a mechanical stress-gradient induced backflow has a profound impact on the characteristics of electromigration failure. Here we review our recent studies of electromigration failure at short lengths in Cu/low-k interconnects.

Nettet29. aug. 2013 · The line length at which EM will not occur, is pretty short. I don't know what it is in any particular technology, but people make electromigration-mode fuses at lesser length. If you are within ratings, you should be fine, provided those ratings include random defectivity like notching, and not-random but variable things like thinning over ... NettetTherefore, it would be quite natural to define the flow of charge in terms of current per unit area or unit length, which is called current density. In this article, we will consider the difference between electric current and current density and the importance of achieving, maintaining, and measuring proper current density in various applications of electrical …
NettetDefinition Electromigration is the movement of atoms based on the flow of current through a material. If the current density is high enough, the heat dissipated within the material will repeatedly break atoms from the … 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 …

Nettet14. apr. 2024 · Recently, we detected length-dependent electromigration (EM) behavior in Sn-58Bi (SB) solder and revealed the existence of Bi back-flow, which retards EM-induced Bi segregation and is dependent on solder length. The cause of the back-flow is attributed to an oxide layer formed on the SB solder.
