Electromigration

Flying electrons can make ions to move in the crystalical net, if to much of they do this in specific place then path brake. It's a problem with too thin paths and too big currents :)
 

Re: Electromigration

Here's a source of much more information about electromigration:

Go to http://www.dogpile.com/

Type "electromigration" (without the quotes) in the box and either click the 'Search' button or hit <Enter> on your keyboard.

I got four pages of good references. (Dogpile searches all the top search sites and gives great results. You can set it to show you which search engine gave which result too.)

About your 'What is it?' question, here's a good answer in simple language (and some good pictures):

http://www.siliconfareast.com/emig.htm

"Electromigration refers to the gradual displacement of the metal atoms of a conductor as a result of the current flowing through that conductor. The process of electromigration is analogous to the movement of small pebbles in a stream from one point to another as a result of the water gushing through the pebbles."

Another very good result of the dogpile search is this white paper:
