    摘要: A received layout identifies a plurality of circuit components to be included in an integrated circuit (IC) layer for double patterning the layer using two photomasks, the layout including a plurality of first patterns to be included in the first photomask and at least one second pattern to be included in the second photomask. A selected one of the first patterns has first and second endpoints, to be replaced by a replacement pattern connecting the first endpoint to a third endpoint. At least one respective keep-out region is provided adjacent to each respective remaining first pattern except for the selected first pattern. Data are generated representing the replacement pattern, such that no part of the replacement pattern is formed in any of the keep-out regions. Data representing the remaining first patterns and the replacement pattern are output.

    摘要: A method includes extracting a first netlist from a first layout of a semiconductor circuit and estimating layout-dependent effect data based on the first netlist. A first simulation of the semiconductor circuit is performed based on the first netlist using an electronic design automation tool, and a second simulation of the semiconductor circuit is performed based on a circuit schematic using the electronic design automation tool. A weight and a sensitivity of the at least one layout-dependent effect are calculated, and the first layout of the semiconductor circuit is adjusted based on the weight and the sensitivity to provide a second layout of the semiconductor circuit. The second layout is stored in a non-transient storage medium.

    摘要: In a semiconductor device design method performed by at least one processor, first and second electrical components are extracted from a layout of a semiconductor device. The semiconductor device has a semiconductor substrate and the first and second electrical components in the semiconductor substrate. Parasitic parameters of a coupling in the semiconductor substrate between the first and second electrical components are extracted using a first tool. Intrinsic parameters of the first and second electrical components are extracted using a second tool different from the first tool. The extracted parasitic parameters and intrinsic parameters are combined into a model of the semiconductor device. The parasitic parameters of the coupling are extracted based on a model of the coupling included in the second tool.

    摘要: The present disclosure relates to a method and apparatus for identifying pre-coloring violations and for providing hints and/or warnings to a designer to eliminate the pre-coloring violations. In some embodiments, the method is performed by identifying G0-spaces within a double patterning technology (DPT) layer, of an integrated chip (IC) layout, having a plurality of pre-colored shapes. Violation paths extending between the pre-colored shapes are identified based upon the G0-spaces. Good paths (i.e., paths that will not cause a violation) and bad paths (i.e., paths that will cause a violation) between the pre-colored shapes are also identified. Hints and/or warnings are generated based upon the identified good and bad paths, wherein the hints and/or warnings provide guidance to eliminate the violation paths and develop a violation free IC layout.

    摘要: A method of designing a double patterning mask set for a layout of a chip includes designing standard cells. In each of the standard cells, all left-boundary patterns are assigned with one of a first indicator and a second indicator, and all right-boundary patterns are assigned with an additional one of the first indicator and the second indicator. The method further includes placing the standard cells in a row of the layout of the chip. Starting from one of the standard cells in the row, indicator changes to the standard cells are propagated throughout the row. All patterns in the standard cells having the first indicator are transferred to a first mask of the double patterning mask set. All patterns in the standard cells having the second indicator are transferred to a second mask of the double patterning mask set.

    摘要: A method includes receiving an identification of a plurality of circuit components to be included in an IC layout. Data are generated representing a first pattern to connect two of the circuit components. The first pattern has a plurality of segments. At least two of the segments have lengthwise directions perpendicular to each other. At least one pattern-free region is reserved adjacent to at least one of the at least two segments. Data are generated representing one or more additional patterns near the first pattern. None of the additional patterns is formed in the pattern-free region. The first pattern and the additional patterns form a double-patterning compliant set of patterns. The double-patterning compliant set of patterns are output to a machine readable storage medium to be read by a system for controlling a process to fabricate a pair of masks for patterning a semiconductor substrate using double patterning technology.
