  • Patent number: 11934106
    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.

  • Publication number: 20100225867
    Abstract: A TFT array substrate includes a plurality of gate lines, common lines, data lines and pixel electrodes. Each common line includes a common electrode which is perpendicular to the gate line and has a first width. The data line has a second width and is perpendicular to the gate line, wherein two adjacent gate lines and two adjacent data lines define a pixel. The pixel electrodes are located in the pixels respectively, wherein the common electrode is overlapped with the data line and a part of the pixel electrode, and the common electrode completely shelters a gap between the pixel electrode and the data line.
