  • Patent number: 8914755
    Abstract: Among other things, one or more techniques and systems for layout re-decomposition of a new layout corresponding to a change order to an original layout associated with an integrated circuit are provided. The change order is applied to the original layout to create the new layout. The original layout comprises one or more original pattern portions assigned pattern colors that correspond to pattern masks. One or more new pattern portions within the new layout are assigned pattern colors such that the new layout has a relatively high color similarity with respect to the original layout. In this way, changes to the pattern masks are reduced, thus mitigating fabrication delay or costs that would otherwise result from significant changes to the pattern masks.

  • Patent number: 8875067
    Abstract: The present disclosure relates to a method of forming a reusable cut mask or trim mask that can be used for multiple design levels, and an associated apparatus. In some embodiments, the method is performed by determining positions of a plurality of mask cuts for a reusable cut mask or a reusable trim mask. Shapes are then routed along a routing path having a plurality of design levels. The routing path intersects one or more of the plurality of mask cuts at positions that form distinct shapes that connect nodes of an integrated chip sharing a same electric network. By routing shapes on a plurality of design levels to intersect one or more of the plurality of mask cuts, the cut masks can be reused between the plurality of levels, therefore decreasing mask costs during fabrication.

  • Patent number: 8863066
    Abstract: High performance clock distributions and similar wiring networks require improvements in reliability and performance. This is especially true when hierarchical wiring with different metal thicknesses is employed and when a smaller number of large, higher-power buffers are used to reduce timing variability. Routing of critical nets improves robustness, reliability, and resistance while minimizing track and power usage. The method further optimizes the use of multiple physical pins on buffers to achieve desired electrical criteria. This involves optimal selection of additional routing beyond what is needed to satisfy simple connectivity. The routing involves an iterative process to select and evaluate additional possible routes on multiple layers. Each iteration involves extraction and simulation or estimation, and additional routes are added until the desired electrical criteria are met.

  • Patent number: 8854561
    Abstract: A LCD panel in which a pixel has a first sub-pixel area and a second sub-pixel area, each area having a storage capacitor. Each pixel has a first gate line for providing a first gate-line signal for charging the first and second storage capacitors, and a second gate line for providing a second gate-line signal for removing part of the charges in the second storage capacitor to a third capacitor after the first gate-line signal has passed. The width of the first and second gate-line signals and their timing can be varied so that the first gate-line signal provided to a row can be used as the second gate-line signal to one of the preceding rows. In some embodiments, a pixel in each row has a duplicate pixel arranged to similarly receive the first and second gate-line signals, but data signals are received from different data lines.

  • Patent number: 8850368
    Abstract: One or more techniques or systems for determining double patterning technology (DPT) layout routing compliance are provided herein. For example, a layout routing component of a system is configured to assign a pin loop value to a pin loop. In some embodiments, the pin loop value is assigned based on a mask assignment of a pin of the pin loop. In some embodiments, the pin loop value is assigned based on a number of nodes associated with the pin loop. DPT compliance or a DPT violation is determined for the pin loop based on the pin loop value. In this manner, odd loop detection associated with DPT layout routing is provided because a DPT violation results in generation of an additional instance of a net, for example. Detecting an odd loop allows a design to be redesigned before fabrication, where the odd loop would present undesired issues.

  • Publication number: 20140282344
    Abstract: Some embodiments of the present disclosure relates to a method and apparatus to achieve a layout that is compatible with a multiple-patterning process. Two or more unit cells are constructed with layouts which satisfy the properties of the multiple-patterning process, and are each decomposed into two or more colors to support the multiple-patterning process. An active layout feature is merged with a dummy wire at a shared boundary between two unit cells. In the event of a short between two active layout features at the shared boundary, an automatic post-layout method can rearrange the layout features in a vicinity of the shared boundary to separate the active layout features to achieve cell functionality while satisfying the multiple-patterning properties.
