    Abstract: An ESD guard ring structure includes numerous first fin structures, numerous second fin structures, numerous first polysilicon conductive lines, numerous second polysilicon conductive lines, numerous third polysilicon conductive lines and numerous single diffusion breaks. Each of the first fin structures includes at least one single diffusion break therein. Each of the single diffusion breaks overlaps one of the third polysilicon conductive lines.

    Abstract: A method includes providing a layout pattern to a computer system. The layout pattern includes a first pattern, a second pattern, and a third pattern. A central line defined by connecting a line end of the second pattern and a line end of the third pattern overlaps with a middle portion of the first pattern. An optical proximity correction (OPC) is performed on the layout pattern to form a first auxiliary pattern. The first auxiliary pattern includes a first stripe pattern and a second stripe pattern both extending from the line end of the second pattern. The second stripe pattern is closer to the first pattern than the first stripe pattern, and an extending length of the second stripe pattern is less than an extending length of the first stripe pattern. The layout pattern and the first auxiliary pattern are outputted through the computer system onto a photomask.

    Abstract: A photomask structure having a first region and a second region is provided. The layout pattern density of the first region is smaller than the layout pattern density of the second region. The photomask structure includes a first layout pattern, a second layout pattern, and first assist patterns. The first layout pattern is located in the first region and the second region. The second layout pattern is located in the second region. The second layout pattern is located on one side of the first layout pattern. The first assist patterns are located on the first sidewall of the first layout pattern and separated from each other. The first sidewall is adjacent to the second layout pattern. The first assist patterns are adjacent to a boundary between the first region and the second region. The lengths of two adjacent first assist patterns decrease in the direction away from the boundary.

    Abstract: A method for a semiconductor layout pattern decomposition includes following steps. (a) receiving a semiconductor layout pattern; (b) performing a first separation/decomposition to the semiconductor layout pattern to obtain a grille pattern and a non-grille pattern; (c) recognizing a plurality of intersection regions in the grille pattern and alternately marking the intersection regions with a first region and a second region; (d) performing a second separation/decomposition to the grille pattern to obtain a plurality of first sub-patterns and a plurality of second sub-patterns perpendicular to each other, the first sub-patterns including the first regions, the second sub-patterns including the second regions; and (e) introducing a plurality of first assistance features on the first regions in the first sub-patterns and on the second regions on the second regions in the second sub-patterns, respectively. The step (a) to the step (e) are implemented using a computer.
