hi, i would like to know the diff. b/w the materials for nwell and n-diff bcoz while making bulk/substrate connection for pmos we use :
metal + contact + n-diff + nseltap (this is just to mark active region for tapping connection) + nwell .
my question is why we are using extra layer of n-diff here.
