    Abstract: A non-transitory, computer readable storage medium is encoded with computer program instructions, such that, when the computer program instructions are executed by a computer, the computer performs a method. The method generates mask assignment information for forming a plurality of patterns on a layer of an integrated circuit (IC) by multipatterning. The mask assignment information includes, for each of the plurality of patterns, a mask assignment identifying which of a plurality of masks is to be used to form that pattern, and a mask assignment lock state for that pattern. User inputs setting the mask assignment of at least one of the plurality of patterns, and its mask assignment lock state are received. A new mask assignment is generated for each of the plurality of patterns having an “unlocked” mask assignment lock state.

    Abstract: 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.

    Abstract: A method includes receiving data representing a layout of a DPT-layer of an integrated circuit generated by a place and route tool. The layout includes a plurality of polygons to be formed in the DPT-layer by a multi-patterning process. First and second ones of the plurality of polygons to be formed using first and second photomasks, respectively are identified. Any intervening polygons along a first path connecting the first polygon to the second polygon, and separator regions between adjacent polygons along the first path are identified. The separator regions have sizes less than a minimum threshold distance between polygons formed on the first photomask. The separator regions are counted. A multi-patterning conflict is identified, if the count of separator regions is even, prior to assigning all remaining ones of the plurality of polygons to the first or second masks.

    Abstract: In some embodiments, an initial circuit arrangement is provided. The initial circuit arrangement includes cells that include default-rule lines and non-default-rule lines. Line widths of the default-rule lines are selectively increased for a first cell in the initial circuit arrangement, thereby providing a first modified circuit arrangement. A first maximum capacitance value is calculated for the first cell of the first modified circuit arrangement. A second modified circuit arrangement is provided by selectively increasing line widths of the non-default-rule lines in the first modified circuit arrangement. A second maximum capacitance value is calculated for the first cell of the second modified circuit arrangement. A line width of a first non-default-rule line is selectively reduced based on whether the first maximum capacitance value adheres to a predetermined relationship with the second maximum capacitance value. The second modified circuit arrangement is manufactured on a semiconductor substrate.

    Abstract: The present disclosure relates to a method and apparatus for forming a multiple patterning lithograph (MPL) compliant integrated circuit layout by operating a construction validation check on unassembled IC cells to enforce design restrictions that prevent MPL conflicts after assembly. In some embodiments, the method is performed by generating a plurality of unassembled integrated circuit (IC) cells having a multiple patterning design layer. A construction validation check is performed on the unassembled IC cells to identify violating IC cells having shapes disposed in patterns comprising potential multiple patterning coloring conflicts. Design shapes within a violating IC cell are adjusted to achieve a plurality of violation free IC cells. The plurality of violation free IC cells are then assembled to form an MPL compliant IC layout. Since the MPL compliant IC layout is free of coloring conflicts, a decomposition algorithm can be operated without performing a post assembly color conflict check.
