  • Patent number: 9401343
    Abstract: A method of processing a semiconductor wafer includes forming semiconductor dies in the semiconductor wafer, each die having an active region containing devices of an integrated circuit and an edge region surrounding the active region, adjacent ones of the dies being separated by a scribe line. The method further includes forming interconnect wiring over the active region of each semiconductor die in an interlayer dielectric, forming ancillary wiring over the edge region of each die in the interlayer dielectric, forming a passivation on the interlayer dielectric, forming bond pads over the interconnect wiring of each die, the bond pads of each die being in electrical connection with the interconnect wiring of that die, and forming additional bond pads over the ancillary wiring of each semiconductor die, the additional bond pads of each die being in electrical connection with the interconnect wiring of that die.

  • Patent number: 8994148
    Abstract: A semiconductor die includes a semiconductor substrate having an edge region surrounding an active region, the active region containing devices of an integrated circuit. The semiconductor die further includes interconnect wiring over the active region in an interlayer dielectric and electrically connected to the devices in the active region, and ancillary wiring over the edge region in the interlayer dielectric and isolated from the interconnect wiring and the devices in the active device region. The interlayer dielectric is passivated, and bond pads are provided over the interconnect wiring and electrically connected to the interconnect wiring through openings in the passivation over the active region. Additional bond pads are provided over the ancillary wiring and are electrically connected to the interconnect wiring through additional openings in the passivation over the active region.
