摘要: A bonding pad structure includes a substrate and a first conductive island formed in a first dielectric layer and disposed over the substrate. A first via array having a plurality of vias is formed in a second dielectric layer and disposed over the first conductive island. A second conductive island is formed in a third dielectric layer and disposed over the first via array. A bonding pad is disposed over the second conductive island. 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. No other conductive island in the third dielectric layer is connected to the first via array except the second conductive island.
