    摘要: Integrated circuit libraries include a first standard cell having a first left boundary and a first right boundary, and a second standard cell having a second left boundary and a second right boundary. The first standard cell and the second standard cell are of a same cell variant. A first active region in the first standard cell has a different length of diffusion than a second active region in the second standard cell. The first active region and the second active region are corresponding active regions represented by a same component of a same circuit diagram representing both the first standard cell and the second standard cell.

    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.

    摘要: A method and apparatus for achieving multiple patterning compliant technology design layouts is provided. An exemplary method includes providing a routing grid having routing tracks; designating each of the routing tracks one of at least two colors; applying a pattern layout having a plurality of features to the routing grid, wherein each of the plurality of features corresponds with at least one routing track; and applying a feature splitting constraint to determine whether the pattern layout is a multiple patterning compliant layout. If the pattern layout is not a multiple patterning compliant layout, the pattern layout may be modified until a multiple patterning compliant layout is achieved. If the pattern layout is a multiple patterning compliant layout, the method includes coloring each of the plurality of features based on the color of each feature's corresponding at least one routing track, thereby forming a colored pattern layout, and generating at least two masks with the features of the colored pattern layout. Each mask includes features of a single color.
