  • Patent number: 10852648
    Abstract: According to one embodiment, a mask pattern correction system includes the following configuration. A stress analysis circuitry divides a layout of a circuit pattern formed using a design mask formed in accordance with mask design data into correction regions, and acquires a displacement amount from the regions. A correction value calculation circuitry calculates a displacement correction value from the displacement amount. A correction map generation circuitry generates a correction map based on a correction value difference of the displacement correction values. A mask position correction circuitry allocates the regions to a layout of the circuit pattern, performs displacement correction of a mask pattern on the design mask by the displacement correction values, and creates a correction mask based on the displacement correction.
