Abstract
A standard cell, placed between a power rail and a ground rail in an integrated circuit, has active areas with connecting arms that extend beneath the power rail and ground rail. The connecting arms conduct current between the power and ground rails and the source regions of transistors in the active areas. The connecting arms include segments extending from these source regions to points beneath the power and ground rails, and segments running longitudinally beneath the power and ground rails. The connecting arms replace metal wiring that would otherwise be required, enabling the size of the standard cell to be reduced.
