  • Patent number: 7345305
    Abstract: A device, system and method for evaluating reliability of a semiconductor chip are disclosed. Strain is determined at a location of interest in a structure. Failures are evaluated in a plurality of the structures after stress cycling to determine a strain threshold with respect to a feature characteristic. Structures on a chip or chips are evaluated based on the feature characteristic to predict reliability based on the strain threshold and the feature characteristic. Predictions and design changes may be made based on the results.

  • Patent number: 7163883
    Abstract: An edge seal around the periphery of an integrated circuit device which environmentally protects the copper circuitry from cracks that may form in the low-k interlevel dielectric during dicing. The edge seal essentially constitutes a dielectric wall between the copper circuitry and the low-k interlevel dielectric near the periphery of the integrated circuit device. The dielectric wall is of a different material than the low-k interlevel dielectric.

  • Patent number: 5976970
    Abstract: A method of forming electrical conductors having sub-half-micron geometries and using a high yield process is described. Trenches provided with an overhang are positioned where a metal interconnection is to be formed. A composite insulator layer is deposited and is followed by laterally filling with metal the trench under the overhang. Excess metal is then chem-mech polished. Only the non-crucial neck of the metal wiring is left exposed during polishing. Since spacing between the exposed metal lines is increased, it requires longer distances for the metal to smear and cause unwanted shorts. Three methods are described to laterally fill the trenches under the overhang. A first method describes the process parameters to achieve lateral deposition by high surface mobility and low sticking coefficient. A second method teaches a technique of inducing micro-creep to laterally fill the trenches under the overhang.
