  • Patent number: 9425095
    Abstract: A system and method for a distributed metal routing is disclosed. An embodiment comprises a metal_0 layer with a metal_1 layer overlying the metal_0 layer. The metal_1 layer comprises separate parallel lines, with lines having different signals being distributed across the metal_1 layer. Such a layout decreases the parasitic resistance within the metal_0 layer as it decreases the distance current travels. Additionally, the distributed layout in metal_1 allows connections to be made to a metal_2 layer without the need for a hammer head connection of vias.
