    摘要: A process and apparatus are provided for automated pattern-based semiconductor design layout correction. Embodiments include scanning a drawn semiconductor design layout to determine a difficult-to-manufacture pattern within the drawn semiconductor design layout based on a match with a pre-characterized difficult-to-manufacture pattern, determining a corrected pattern based on a pre-determined correlation between the corrected pattern and the pre-characterized difficult-to-manufacture pattern, and replacing the difficult-to-manufacture pattern with the corrected pattern within the drawn semiconductor design layout.

    摘要: Methods for fabricating semiconductor devices are provided. In an embodiment, a method of fabricating a semiconductor device includes scanning a circuit design layout and proposing patterns for decomposed layouts. The proposed patterns are then compared with a library of prior patterns including a category of forbidden patterns and a category of preferred patterns. If a selected proposed pattern matches a forbidden pattern, the selected proposed pattern is eliminated. If the selected proposed pattern matches a preferred pattern, then the selected proposed pattern is identified for use in the decomposed layouts. Decomposed layouts are generated from the identified patterns. A plurality of masks is fabricated based on the decomposed layouts. Then a multiple patterning lithographic technique is performed with the plurality of masks on a semiconductor substrate.

    摘要: Layout patterns are identified as problematic when they have particular parameters required to exceed standard limits. The problematic layout patterns are associated with preferred design rules in a DRC-Plus deck. Layout data is scanned to generate match locations of any problematic layout patterns. The match locations are forwarded to a DRC engine that compares layout parameters of the match locations to corresponding preferred layout rules in the DRC-Plus deck. The DRC-Plus check results are used to modify the layout to improve manufacturability of the layout.

    摘要: A method includes specifying a plurality of optical proximity correction metrology sites on a wafer. Metrology data is collected from at least a subset of the metrology sites. Data values are predicted for the subset of the metrology sites using an optical proximity correction design model. The collected metrology data is compared to the predicted data values to generate an optical proximity correction metric. A problem condition associated with the optical proximity correction design model is identified based on the optical proximity correction metric.
