The present invention adds one or more thick layers of polymer dielectric and one or more layers of thick, wide metal lines on top of a finished semiconductor wafer, post passivation. The thick, wide metal lines may be used for long signal paths and can also be used for power buses or power planes, clock distribution networks, critical signal, and re-distribution of I/O pads for flip chip applications. Photoresist define electroplating, sputter/etch, or dual and triple damascene techniques are used for forming the metal lines and via fill.
