  • Patent number: 9698080
    Abstract: A three-dimensional semiconductor device using redundant bonding-conductor structures to make inter-level electrical connections between multiple semiconductor chips is disclosed. A first chip, or other semiconductor substrate, forms a first active area on its upper surface, and a second chip or other semiconductor substrate forms a second active area on its upper surface. According to the present invention, when the second chip has been mounted above the first chip, either face-up or face-down, the first active area is coupled to the second active area by at least one redundant bonding-conductor structure. In one embodiment, each redundant bonding-conductor structure includes at least one via portion that extends completely through the second chip to perform this function. In another, the redundant bonding-conductor structure extends downward to the top level interconnect. The present invention also includes a method for making such a device.
