Could somebody throw some light on how TSMCN90RF mim caps are made?
I can see some layers call CBM, CTM etc.. but didn't understand how it will be on silicon.
MIM Capacitor is the capacitor between two metal.
Some layers are dummy layer for MIM Cap.
For example, if the capactior is constructed between M8 and M7, then the M7 density check would exclude the CBM region
Oh sorry, I think I was wrong with the metals !
forget it.
We used to connect top and bot connections to the top metal layer (in your case it is the M6), but it was a different case
