Abstract:
1. A bonding pad structure, comprising: a substrate; a first conductive island in a first dielectric layer over the substrate; a first via array having a plurality of vias in a second dielectric layer over the first conductive island; a second conductive island in a third dielectric layer over the first via array; a second via array having a plurality of vias in a fourth dielectric layer over the second conductive island; a plurality of third conductive islands in a fifth dielectric layer over the second via array, the third conductive islands of the plurality of third conductive islands each being separated from one another by dielectric material of the fifth dielectric layer and in contact with one via of the second via array; and a bonding pad over the third conductive islands of the plurality of third conductive islands, the third conductive islands of the plurality of third conductive islands being in contact with the bonding pad, wherein the first conductive island, the first via array, and the second conductive island are electrically connected to the bonding pad, the first via array is connected to no other conductive island in the first dielectric layer except the first conductive island and no other conductive island in the third dielectric layer is connected to the first via array except the second conductive island.
