  • Patent number: 7573097
    Abstract: The specification describes an improved mechanical electrode structure for MOS transistor devices with elongated runners. It recognizes that shrinking the geometry increases the likelihood of mechanical failure of comb electrode geometries. The mechanical integrity of a comb electrode is improved by interconnecting the electrode fingers in a cross-connected grid. In one embodiment, the transistor device is interconnected with gate fingers on a lower metaliization level, typically the first level metal, with the drain interconnected at a higher metal level. That allows the drain fingers to be cross-connected with a vertical separation between drain and gate comb electrodes. The cross-connect members may be further stabilized by adding beam extensions to the cross-connect members. The beam extensions may be anchored in an interlevel dielectric layer for additional support.

  • Patent number: 7339274
    Abstract: Phenomena such as electromigration and stress-induced migration occurring in metal interconnects of devices such as integrated circuits are inhibited by use of underlying non-planarities. Thus the material underlying the interconnect is formed to have non-planarities typically of at least 0.02 ?m in height and advantageously within 100 ?m of another such non-planarity. Such non-planarities, it is contemplated, reduce grain boundary movement in the overlying interconnect with a concomitant reduction in void aggregation.
