    Abstract: Disclosed is a mask data processing method of correcting a hierarchical structure. In the case that in design data having a hierarchical structure including a plurality of cells each having a design pattern, when the total number of graphic forms or the total edge length of a design pattern on which the calculation of mask data processing is to be executed, the amount of calculation to be executed, or the expansion degree presumably becomes equal to or larger than a predetermined threshold value if the calculation of the mask data processing is executed on the design data having the initial hierarchical structure, the hierarchical structure is corrected. This correction is performed to reduce the total number of graphic forms or the total edge length of the design pattern on which the calculation is to be executed, the amount of calculation to be executed, of the expansion degree.

  • Patent number: 7614026
    Abstract: A pattern of a desired size is formed on a semiconductor substrate by the following procedure. A property, including at least one of an aberration of an exposure device, a property of an illumination, a property of a projection lens, and a pattern coverage in a shot, are allocated, in a first database, to predetermined positions assigned in a chip. A second database is prepared by pairing a cell name of a cell extracted from hierarchical processing of a design pattern and arrangement positional data of the cell. The property data is allocated to the cell based on the first and second databases. Mask data processing based on at least one of the property data is executed, and the cell subjected to the mask data processing is rearranged on the chip.
