    摘要: In the method of correcting a mask pattern according to the embodiments, a mask pattern correction amount for a reference flare value is calculated as a reference mask correction amount, for every type of patterns within the layout, and a change amount of the mask pattern correction amount corresponding to the change amount of the flare value is calculated as the change amount information. A mask pattern corresponding to the flare value of the pattern is created based on the reference mask correction amount and the change amount information corresponding to the pattern, extracted from the information having the pattern, the reference mask correction amount, and the change amount information correlated with each other, and based on a difference between the flare value of the pattern and the reference flare value.

    摘要: According to one embodiment, a semiconductor device includes interconnects extending from a element formation area to the drawing area, and connected with semiconductor elements in the element formation area and connected with contacts in the drawing area. The interconnects are formed based on a pattern of a (n+1)th second sidewall film matching a pattern of a nth (where n is an integer of 1 or more) first sidewall film on a lateral surface of a sacrificial layer. A first dimension matching an interconnect width of the interconnects and an interconnects interval in the element formation area is (k1/2n)×(λ/NA) or less when an exposure wavelength of an exposure device is λ, a numerical aperture of a lens of the exposure device is NA and a process parameter is k1. A second dimension matching an interconnect interval in the drawing area is greater than the first dimension.

    摘要: 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.
