Abstract:
Embodiments described herein provide approaches for improving a standard cell connection for circuit routing. Specifically, provided is an IC device having a plurality of cells, a first metal layer (M1) pin coupled to a contact bar extending from a first cell of the plurality of cells, and a second metal layer (M2) wire coupled to the contact bar, wherein the contact bar extends across at least one power rail. By extending the contact bar into an open area between the plurality of cells to couple the M1 pin and the M2 wire, routing efficiency and chip scaling are improved.
