20140353842 | WIDE PIN FOR IMPROVED CIRCUIT ROUTING - Embodiments described herein provide approaches for improved circuit routing using a wide-edge pin. Specifically, provided is an integrated circuit (IC) device comprising a standard cell having a first metal layer (M1) pin coupled to a second metal layer (M2) wire at a via. The M1 pin has a width greater than a width of the via sufficient to satisfy an enclosure rule for the via, while the M1 pin extends vertically past the via a distance substantially equal to or greater than zero. This layout increases the number of available pin access points within the standard cell and thus improves routing efficiency and chip size. | 12-04-2014 |
