Electromigration Early Resistance Increase Measurements

Although a lot of work has been performed on electromigration, it is still not at present well understood, and a more detailed understanding of the electromigration process is de\ired. The most accepted method for electromigr ation testing has been conventional life-testing of samples until a particular failure condition is reached. Although this method gives information such a\ median time to failure and activation energies, it does not tell much about a particular subpopulation of the failures which is particularly interesting. the early failure distribution.
