  • Patent number: 9000876
    Abstract: An inductor device and method of forming the inductor device are provided. In some embodiments the inductor device includes a post passivation interconnect (PPI) layer disposed and an under bump metallization (UBM) layer, each disposed over a substrate. The PPI layer forms a coil and dummy pads. The dummy pads are disposed around a substantial portion of the coil to shield the coil from electromagnetic interference. A first portion of the UBM layer is electrically coupled to the coil and configured to interface with an electrical coupling member.

  • Patent number: 8994181
    Abstract: Mechanisms of forming a bond pad structure are provided. The bond pad has a recess region, which is formed by an opening in the passivation layer underneath the bond pad. An upper passivation layer covers at least the recess region of the bond pad to reduce trapping of patterning and/or etching residues in the recess region. As a result, the likelihood of bond pad corrosion is reduced.
