  • Patent number: 10068806
    Abstract: At least one method, apparatus and system disclosed involves providing an integrated circuit having metal feature flyover over an middle-of-line (MOL) feature. A first location for a non-contact intersection region between a first middle of line (MOL) interconnect feature and a metal feature in a functional cell is determined. A dielectric feature is formed over the first MOL interconnect feature at the first location. The metal feature is formed over the dielectric layer, the dielectric layer providing a predetermined amount of voltage isolation between the first MOL interconnect feature and the metal feature.

  • Patent number: 9666488
    Abstract: A method of forming a silicide layer as a pass-through contact under a gate contact between p-epilayer and n-epilayer source/drains and the resulting device are provided. Embodiments include depositing a semiconductor layer over a substrate; forming a pFET gate on a p-side of the semiconductor layer and a nFET gate on a n-side of the semiconductor layer; forming a gate contact between the pFET gate and the nFET gate; forming raised source/drains on opposite sides of each of the pFET and nFET gates; and forming a metal silicide over a first raised source/drain on the p-side and over a second raised source/drain on the n-side, wherein the metal silicide extends from the first raised source/drain to the second raised source/drain and below the gate contact between the pFET and nFET gates.

  • Patent number: 8689154
    Abstract: An approach for providing timing-closed FinFET designs from planar designs is disclosed. Embodiments include: receiving one or more planar cells associated with a planar design; generating an initial FinFET design corresponding to the planar design based on the planar cells and a FinFET model; and processing the initial FinFET design to provide a timing-closed FinFET design. Other embodiments include: determining a race condition associated with a path of the initial FinFET design based on a timing analysis of the initial FinFET design; and increasing delay associated with the path to resolve hold violations associated with the race condition, wherein the processing of the initial FinFET design is based on the delay increase.
