    What if fin width of finfet will adjust..

    why the width of the fin of finfet was fixed..?what are the limitations for fixing width of the fin ?and what if change the width of the fin of finfet..?

    because the foundry said so. you go with it. your knob is the number of fins, not their width.

    thank you for your reply "not sam"...i know we can't change fin width but why foundry stick with that and what are the consequences we will face if fin width changes..?

    Fin width cannot change, at least not in the 5 FinFET technologies I have had access to. You have to understand that process engineers spent years optimizing the process for that specific width, this is not something a designer is going to play with. If, and this is a wild scenario, the fin width were to change, there would be consequences for device performance, leakage, pin/contacts, effective gate area, and so on. It would be a completely new technology, or almost.
