  • Structure for reducing cross-talk in VLSI circuits and method of making same using filled channels to minimize cross-talk
    Patent number: 6218631
    Abstract: A structure for reducing cross-talk in VLSI circuits is disclosed. By filling voltage and ground metal lines in free or unused channels of VLSI chips and connecting them efficiently to the regular power image of the chip, the line to line coupling through vertical layers is reduced almost to zero and in-layer line to line coupling is also drastically reduced.
