Abstract:
1. A standard cell having a rectangular cell boundary and comprising a plurality of transistors formed on a substrate between a first rail and a second rail, one of the first rail and the second rail extending laterally along an edge of the rectangular cell boundary and supplying a power supply potential to the standard cell, another one of the first rail and the second rail extending laterally along another edge of the rectangular cell boundary and supplying a ground potential to the standard cell, the standard cell including a first active area in which a first transistor of the plurality of transistors is formed, wherein the first active area extends along and in proximity to the edge of the rectangular cell boundary and has a first connecting arm extending substantially beneath the first rail, the first rail being connected to the first connecting arm of the first active area, and wherein the first connecting arm is doped with an impurity and conducts current between the first rail and the first transistor.
