  • Patent number: 7679180
    Abstract: An improved via arrangement for a bonding pad structure is disclosed comprising an array of vias surrounded by a line via. The line via provides a barrier to cracks in the dielectric layer encompassing the via array. Although cracks are able to spread relatively unhindered between the vias of the via array, they are blocked by the line via and thus can not spread to neighboring regions of the chip or wafer. The line via can be provided in a variety of shapes and dimensions, to suit a desired application. Additionally, due to its substantially uninterrupted length, the line via provides added strength to the bond pad.

  • Patent number: 7659632
    Abstract: Solder bump structures for semiconductor device packaging is provided. In one embodiment, a semiconductor device comprises a substrate having a bond pad and a first passivation layer formed thereabove, the first passivation layer having an opening therein exposing a portion of the bond pad. A metal pad layer is formed on a portion of the bond pad, wherein the metal pad layer contacts the bond pad. A second passivation layer is formed above the metal pad layer, the second passivation layer having an opening therein exposing a portion of the metal pad layer. A patterned and etched polyimide layer is formed on a portion of the metal pad layer and a portion of the second passivation layer. A conductive layer is formed above a portion of the etched polyimide layer and a portion of the metal pad layer, wherein the conductive layer contacts the metal pad layer. A conductive bump structure is connected to the conductive layer.
