    摘要: A method includes providing a layout of an integrated circuit design, and generating a plurality of double patterning decompositions from the layout, with each of the plurality of double patterning decompositions including patterns separated to a first mask and a second mask of a double patterning mask set. A maximum shift between the first and the second masks is determined, wherein the maximum shift is a maximum expected mask shift in a manufacturing process for implementing the layout on a wafer. For each of the plurality of double patterning decompositions, a worst-case performance value is simulated using mask shifts within a range defined by the maximum shift.

    摘要: A method of designing a double patterning mask set includes dividing a chip into a grid comprising grid cells; and laying out a metal layer of the chip. In substantially each of the grid cells, all left-boundary patterns of the metal layer are assigned with a first one of a first indicator and a second indicator, and all right-boundary patterns of the metal layer are assigned with a second one of the first indicator and the second indicator. Starting from one of the grid cells in a row, indicator changes are propagated throughout the row. All patterns in the grid cells are transferred to the double patterning mask set, with all patterns assigned with the first indicator transferred to a first mask of the double patterning mask set, and all patterns assigned with the second indicator transferred to a second mask of the double patterning mask set.

    摘要: A method includes receiving an identification of a plurality of cells to be included in an integrated circuit (IC) layout, including a list of pairs of cells within the plurality of cells to be connected to each other. First routing paths are identified, to connect a maximum number of the pairs of cells using one-dimensional (1-D) routing between cells within those pairs of cells. Second routing paths are selected from a predetermined set of two-dimensional (2-D) routing patterns to connect any of the pairs of cells which cannot be connected by 1-D routing. The first and second routing paths are output to a machine readable storage medium to be read by a control system for controlling a semiconductor fabrication process to fabricate the IC.

    摘要: Efficient and cost-effective systems and methods for detecting and correcting hot spots of semiconductor devices are disclosed. In one aspect, a method for creating a layout from a circuit design is described. The method includes applying a first set of hot spot conditions to a global route to produce a detailed route; applying a second set of hot spot conditions to the detailed route to produce a post-detailed route; and applying a third set of hot spot conditions to the post-detailed route to produce the layout. In another aspect, a method includes providing a circuit design; applying a first hot spot filter to a global routing of the circuit design to produce a detailed route; applying a less pessimistic, second hot spot filter to the detailed route to produce a post-detailed route; and performing a rip-up and reroute of the post-detailed route to produce a final layout.
