  • Methods for modifying an integrated circuit layout design
    Patent number: 8997027
    Abstract: Methods for modifying a layout design of an integrated circuit using model-based retargeting are provided. In one embodiment, a method for modifying an integrated circuit layout design includes providing an initial integrated circuit layout design, correcting the initial layout design for etch-induced lithography errors to generate an etch-corrected layout design, and fragmenting the etch-corrected layout design to generate a fragmented layout design comprising a plurality of fragments. The method further includes performing a bridging condition simulation and a pinching condition simulation on the fragmented layout design and calculating a required movement for at least one fragment of the fragmented layout design based on the bridging condition simulation and the pinching condition simulation.
    Type: Grant
