Abstract:
An integrated circuit has a power rail formed of a first wire in a lower metal layer and a second wire in an upper metal layer and that run in the same direction in their respective layers. A number of vias connect the first and second wires, to form a sandwich power rail structure. Other embodiments are also described and claimed.
