Is there any Idea relationship between life of a cpu based on its manufacturing process (nm). I was in the opinion that fabrication with more nm will last to that of fabrication having lower nm. Here life means till the cpu is totally dead and does not means obsolete. So is there any data about that.

No there is no such relation. And CPU manufactured with lower nm fabrication process generally has lesser power consumption while running at same speed, quite opposite of what you thought of.
