Yousef, I would expect different processes to have different susceptabilities to atomic migration, i.e., diffusion of dopant atoms in various directions. Since this is accelerated by temperature that means different processes will be more or less prey to this thanothers. Small feature modern CPU designs are far more susceptable than older larger feature designs, like TTL or transistors simply because the distances are far larger with these older parts and thus they can tolerate higher temperatures, like 125C, before the suffer from migration.

Does that mean that Intel has some far smaller sections on the die, maybe to make it hit 2 GHZ? and those are the parts that cook to destruction first?
