A semiconductor package includes a semiconductor substrate a semiconductor substrate having source and drain regions formed therein, an intermediate routing structure to provide electrical interconnects to the source and drain regions, a dielectric layer formed over the intermediate routing structure, and an under-bump-metallization (UBM) stack. The intermediate routing structure includes an outermost conductive layer, and the dielectric layer has an opening positioned over a portion of the intermediate layer routing structure. The UBM stack includes a conductive base layer formed over the dielectric layer and electrically connected to the outermost conductive layer through the opening, and a thick conductive layer formed on the base layer. A conductive bump is positioned on the UBM stack and laterally spaced from the opening. |
