  • Patent number: 8719755
    Abstract: Among other things, one or more techniques for graded dummy insertion and a resulting array are provided herein. For example an array is a metal oxide semiconductor (MOS) array, a metal oxide metal (MOM) array, or a resistor array. In some embodiments, a first region and a second region are identified based on a density gradient between a first pattern density associated with the first region and a second pattern density associated with the second region. For example, the first pattern density and the second pattern density are gate densities and/or poly densities. To this end, a dummy region is inserted between the first region and the second region, the dummy region includes a graded pattern density based on a first adjacent pattern density and a second adjacent pattern density. In this manner, graded dummy insertion is provided, thus enhancing edge cell performance for an array, for example.

  • Patent number: 8719759
    Abstract: The present disclosure relates to a method of optimizing the area of series gate layout structures for FinFET devices. The method analyzes an integrated chip (IC) layout to determine a first gate material density along a first direction and to separately determine a second gate material density along a second direction based upon the first gate material density. A number of series gate stages for a FinFET (field effect transistor) device having a gate length along the second direction, is chosen based upon the second gate material density and one or more device performance parameters of the FinFET device. By analyzing the density of gate material in separate directions, the effective length of the gate of the FinFET can be increased without increasing the size of the transistor array.

  • Patent number: 8701055
    Abstract: The present disclosure provides a system and method of designing an integrated circuit. A plurality of devices are selected and properties assigned to each of the plurality of devices. These plural devices having assigned properties are then combined into a macro cell whereby a density gradient pattern is generated for the macro cell. Layout dependent effect (LDE) parameters are determined for the macro cell as a function of the combination of plural devices, and electrical performance characteristics for the macro cell are simulated. A layout distribution of the plurality of devices within the macro cell can then be determined as a function of one or more of the simulated electrical performance characteristics, determined LDE parameters, and generated density gradient pattern. A design layout of an integrated circuit can be generated corresponding to the layout distribution for the macro cell.
