  • Publication number: 20170047259
    Abstract: Integrated circuits and methods of manufacturing such circuits are disclosed herein that feature metal line-via matrix insertion after place and route processes are performed and/or completed for the integrated circuit's layout. The metal line-via matrix consists of one or more additional metal lines and one or more additional vias that are inserted into the integrated circuit's layout at a specific point to lower the current and current density through a first conductive path that has been determined to suffer from electromigration, IR-voltage drop, and/or jitter. Specifically, the metal line-via matrix provides one or more auxiliary conductive paths to divert and carry a portion of the current that would otherwise flow through the first conductive path. This mitigates electromigration issues and IR-voltage drop along the first conductive path. It may also help alleviate problems due to jitter along the path.
