    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: 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: Provided is a system and method for assessing a design layout for a semiconductor device level and for determining and designating different features of the design layout to be formed by different photomasks by decomposing the design layout. The features are designated by markings that associate the various device features with the multiple photomasks upon which they will be formed and then produced on a semiconductor device level using double patterning lithography, DPL, techniques. The markings are done at the device level and are included on the electronic file provided by the design house to the photomask foundry. In addition to overlay and critical dimension considerations for the design layout being decomposed, various other device criteria, design criteria processing criteria and their interrelation are taken into account, as well as device environment and the other device layers, when determining and marking the various device features.

    摘要: A system and method for providing a cell layout for multiple patterning technology is provided. An area to be patterned is divided into alternating sites corresponding to the various masks. During a layout process, sites located along a boundary of a cell are limited to having patterns in the mask associated with the boundary site. When placed, the individual cells are arranged such that the adjoining cells alternate the sites allocated to the various masks. In this manner, the designer knows when designing each individual cell that the mask pattern for one cell will be too close to the mask pattern for an adjoining cell.
