Five-Step (Pad–Pad Short–Pad Open–Short–Open) De-Embedding Method and Its Verification

We present the method for five-step (pad-pad short-pad open-short-open) on-chip parasitic de-embedding. Its validation is verified by gate electrode resistance and input capacitance of transistors based on 45 -nm CMOS process. Optimized dummy structures to remove the parasitic components due to the pad and routing metal are proposed. Parameters extracted by the proposed method have excellent physical and theoretical trends.
