| 摘要 |
An embodiment is a bump bond pad structure that comprises a substrate comprising a top layer, a reinforcement pad disposed on the top layer, an intermediate layer above the top layer, an intermediate connection pad disposed on the intermediate layer, an outer layer above the intermediate layer, and an under bump metal (UBM) connected to the intermediate connection pad through an opening in the outer layer. Further embodiments may comprise a via mechanically coupling the intermediate connection pad to the reinforcement pad. The via may comprise a feature selected from the group consisting of a solid via, a substantially ring-shaped via, or a five by five array of vias. Yet, a further embodiment may comprise a secondary reinforcement pad, and a second via mechanically coupling the reinforcement pad to the secondary reinforcement pad.
