Abstract

In this paper, standard cell design challenges for the 3nm process are introduced, solved, and optimized using the advanced MOL technology, AC P-N connection. In this methodology, each drain nodes of P and NMOS are connected using a single MOL layer (AC). Utilizing the AC P-N connection, standard cell library can be improved in three different ways. First, reduce the parasitic wire resistance by more than 20% and improve circuit reliability by alleviating a high current density. Second, Ceff improvement by composing only the MOL layer (AC) for the output node of the cell improves the standard cell speed up to 9.6%. Third, we propose a novel Flip-Flop (FF) structure optimized for AC P-N connection, thus improving the speed of the FF (1/TD2Q) by 9.1%.
