What Is Electromigration And How To Fix It? |
|
Answer» ELECTROMIGRATION (EM) refer to the phenomenon of movement of metal atoms due to momentum transfer from conducting electrons to metal atoms. Current CONDUCTION over a period of time in a metal route CAUSES opens or shorts due to EM effect. EM effect cannot be avoided. In order to minimize its effect, we use wider wires so that even with EM effect wire STAYS wide enough to conduct over the lifetime of the IC.
