Hi Friends
I have a small dought on using a dummy transistor
as far as i know DUMMY TRANSISTOR is used to match the matched transistor in all aspects including environmental .
mainly we will check to secure DIFFUSION(OD).
But when we are going to lower tech nodes like 22nm 14nm 7nm etc
in matched transistor we will maintain continuous DIFFUSION(OD).
and at end of the matched devies we will get dummy poly . in that under dummy poly we wont have DIFFUSION(OD).
and we will use again dummy transistor
WHY I DONT KNOW.
Kindly explained this Topic please
Thanks in advance
