According to one embodiment, a pattern forming method comprises transferring a pattern formed in a surface of a template to a plurality of chip areas in a semiconductor substrate under different transfer conditions. Furthermore, the transferring the pattern formed in the surface of the template to the plurality of chip areas in the semiconductor substrate under the different transfer conditions comprises transferring the pattern formed in the surface of the template to the semiconductor substrate at least twice under each identical transfer condition. Moreover, the pattern forming method comprises dividing each of the plurality of chip areas into a plurality of areas, determining an optimum condition for each set of corresponding divided areas in the plurality of chip areas, and transferring the pattern onto the semiconductor substrate using the optimum transfer condition determined for each divided area.

According to one embodiment, a template for manufacturing a memory cell array comprising a relievable area and a redundant area replaceable with the relievable area is to be inspected. First, based on a defect position of a defect-detected template and position information on a relievable area, a decision is made as to whether the detected defect is positioned within the relievable area. A decision is made as to whether the number of defect-detected relievable areas exceeds the preset permissible number. When the detected defect is positioned outside the relievable area or when the number of defect-detected relievable areas exceeds the permissible number, a notification that the template has failed the inspection is output.

An electron beam writing method is disclosed, which includes preparing electron beam writing data structured from writing pattern data expressed by both data of VSB shots which are units of shaping beams at the time of carrying out writing a pattern and data of CP shots serving as bases of a repeating pattern, and CP aperture data into which identification numbers IDs and opening positions of respective openings of a CP aperture having openings for VSB shots and openings for CP shots are described, inputting the electron beam writing data to an electron beam writing apparatus, and expanding the electron beam writing data into data of the respective shots defined in the electron beam writing data, determining irradiation times of the respective expanded shots while correcting shot positions, and outputting control signals corresponding to shot data to repeat a shot of a desired pattern, by the electron beam writing apparatus.
摘要:
Using the hierarchy cell5, cell51, cell52, cell4 of the figure cells in the design pattern data, it is not necessary to take the actual forms of patterns and the arrangement information of data (relation between patterns, period of arrangement) into consideration, and therefore, characters for CP exposure can be extracted effectively.
