Ion migration number
Web2 nov. 2015 · The ionic transference number, i.e. the fractional contribution of an ionic species to overall conductivity, strongly depends on cation and anion structure and its … The typical current density at which electromigration occurs in Cu or Al interconnects is 106to 107A/cm2. For solder joints (SnPb or SnAgCu lead-free) used in IC chips, however, electromigration occurs at much lower current densities, e.g. 104A/cm2. It causes a net atom transport along the direction of electron … Meer weergeven Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is … Meer weergeven Electromigration decreases the reliability of integrated circuits (ICs). It can cause the eventual loss of connections or failure of a circuit.
