    摘要: A method of estimating integrated circuit yield comprises providing an integrated circuit layout and a set of systematic defects based on a manufacturing process. Next, the method represents a systematic defect by modifying structures in the integrated circuit layout to create modified structures. More specifically, for short-circuit-causing defects, the method pre-expands the structures when the structures comprise a higher systematic defect sensitivity level, and pre-shrinks the structures when the structures comprise a lower systematic defect sensitivity level. Following this, a critical area analysis is performed on the integrated circuit layout using the modified structures, wherein dot-throwing, geometric expansion, or Voronoi diagrams are used. The method then computes a fault density value, random defects and systematic defects are computed. The fault density value is subsequently compared to a predetermined value, wherein the predetermined value is determined using test structures and/or yield data from a target manufacturing process.

    摘要: Disclosed herein are embodiments of a system and an associated method for analyzing an integrated circuit to determine the value of a particular attribute (i.e., a physical or electrical property) in that integrated circuit. In the embodiments, an open deterministic sequencing technique is used to select a sequence of points representing centers of sample windows in an integrated circuit layout. Then, the value of the particular attribute is determined for each sample window and the results are accumulated in order to infer an overall value for that particular attribute for the entire integrated circuit layout. This sequencing technique has the advantage of allowing additional sample windows to be added and/or the sizes and shapes of the windows to be varied without hindering the quality of the sample.

    摘要: VLSI lithographic fidelity is improved via reducing the pattern space of difficult patterns or structures in a design layout for an integrated circuit design, and thereby increasing the regularity of the design, by converting patterns or structures that are similar but not identical to one another into a smaller set of canonical geometric configurations. By doing so, lithographic processing can be tuned to handle the smaller set of configurations more accurately and efficiently.

    摘要: Methods, systems and program products are disclosed for selectively scaling an integrated circuit (IC) design: by layer, by unit, or by ground rule, or a combination of these. The selective scaling technique can be applied in a feedback loop with the manufacturing system with process and yield feedback, during the life of a design, to increase yield in early processes in such a way that hierarchy is preserved. The invention removes the need to involve designers in improving yield where new technologies such as maskless fabrication are implemented.

    摘要: A method of layout optimization containing parameterized cells includes reading a physical design containing parameterized cells, creating a new version for each of usage of a given parameterized cell. The method optimizes physical design shapes of each new version of the parameterized cell by assigning variables to parameters of the parameterized cell according to a desired objective. Then, the method updates the parameters of each new version of the parameterized cell and replaces each new version of the parameterized cell with an instance of the parameterized cell having updated parameters. The method can optionally adjust physical design shapes based on constraints related to the parameters.
