    摘要: A circuit layout methology is provided for eliminating the extra processing time and file-space requirements associated with the optical proximity correction (OPC) of a VLSI design. The methodology starts with the design rules for a given manufacturing technology and establishes a new set of layer-specific grid values. A layout obeying these new grid requirements leads to a significant reduction in data preparation time, cost, and file size. A layout-migration tool can be used to modify an existing layout in order to enforce the new grid requirements.

The method, at each step, decides if a quick to calculate parameter provides sufficient design margin or if a more accurate but longer to calculate parameter is required.

    摘要: A structure for a semiconductor chip which includes a first region having first cells for storing and processing data, and a second region outside the first region having OPC structures, wherein the OPC structures comprise decoupling capacitors. The line widths of the active gates of first cells are the same size or similar in size as the OPC structures. The OPC structures reduce proximity effects of active devices in the first cells, and comprise N-type FETs and P-type FETs, that are located in the second region. The OPC structures may have a width greater than the first cells. The second region can be multiple OPC structures, whereby the second region comprises multiple decoupling capacitors. The active devices in the first cells are separated by a first distance and the OPC structures are separated from the active devices by the first distance.
