    摘要: A disclosed method for evaluating placement context sensitivity in the design of an integrated circuit includes accessing a standard cell library comprising a database of standard cells and determining generating boundary data for each of the standard cells. The boundary data for a standard cell indicates the layout of features located within boundary regions of the standard cell. The method includes merging or consolidating boundary data for any two standard cells if their boundary data is the same to determine a canonical or minimal set of boundary regions. The disclosed method further includes enumerating and evaluating all combinations of pairs of the canonical boundary regions and, responsive to identifying of a proximity-based sensitivity or exception, modifying, notating, or otherwise remediating the applicable one or more standard cells that correspond to the boundary region combination that raised the exception.

    摘要: A method of generating a design of a reticle for a photolithography process. The reticle may include phase shift features, binary features, and mixed features. The method includes generating a reticle design from a pattern layout and then optimizing the reticle design. In some examples, generating the reticle design includes binning the features of the layout based on feature width. Examples of optimization operations include an over/under operation, an under/over operation, a feature segment expansion operation, a feature edge portion conversation from a binary portion to a phase shift portion, a corner binary segment expansion, a discontinuity removal operation, and a feature dimension change operation that includes a determination of a Mask Error Factor (MEF).

    摘要: A method for improving manufacturability of a design includes performing space or enclosure checks on multiple interacting layers of a layout design and then using the resulting space or enclosure data to move predetermined feature edges in an altered design database to decrease the risk of features widths, feature spaces or feature enclosures being patterned smaller than designed. In some embodiments, the upsized features are larger in the wafer circuit pattern than are drawn in a designed database. The method for improving manufacturability of a design, in some embodiments, is stored on a computer readable storage medium.
