    Abstract: A method of optical proximity correction (OPC) includes the following steps. A layout pattern is provided to a computer system, and the layout pattern is classified into at least a first sub-layout pattern and at least a second sub-layout pattern. Then, at least an OPC calculation is performed respectively on the first sub-layout pattern and the second sub-layout pattern to form a corrected first sub-layout pattern and a corrected second sub-layout pattern. The corrected first sub-layout pattern/the corrected second sub-layout pattern and the layout pattern are compared to select a part of the corrected first sub-layout pattern/the corrected second sub-layout pattern as a first selected pattern/the second selected pattern, and the first selected pattern/the second selected pattern is further altered to modify the corrected first sub-layout pattern/the corrected second sub-layout pattern as a third sub-layout pattern/a fourth sub-layout pattern.

    Abstract: A method for making a photomask layout is provided. A first graphic data of a photomask is provided, wherein the first graphic data includes a first line with a first line end target, a second line with a second line end target and a hole, the first line is aligned with the second line, and the first line, the second line and the hole partially overlap with each other. Thereafter, a retarget step is performed to the first graphic data to obtain a second graphic data, wherein the retarget step includes moving the first line end target and the second line end target in opposite directions away from each other.

    Abstract: An optical proximity correction (OPC) device and method is provided. The OPC device includes an analysis unit, a reverse pattern addition unit, a first OPC unit, a second OPC unit and an output unit. The analysis unit is configured to analyze a defect pattern from a photomask layout. The reverse pattern addition unit is configured to provide a reverse pattern within the defect pattern. The first OPC unit is configured to perform a first OPC procedure on whole of the photomask layout. The second OPC unit is configured to perform a second OPC procedure on the defect pattern of the photomask layout to enhance an exposure tolerance window. The output unit is configured to output the photomask layout which is corrected.

    Abstract: A smooth process is provided in the present invention. The smooth process is applied to a retarget layout, wherein the retarget layout is dissected into a plurality of segments. Furthermore, the retarget layout comprises a first original pattern, a first adding pattern and a second adding pattern. The smooth process includes changing the second adding pattern to a first smooth pattern. Latter, a second smooth pattern is added to extend from a bottom of the first smooth pattern and a tail portion of the first adding pattern is shrunk to a third smooth pattern. After the smooth process, an optical proximity correction process is applied to the smooth layout to produce an optical proximity correction layout.
