    • PROBLEM TO BE SOLVED: To reduce a user's loading accompanying with a character pattern correction work without causing any double exposure by automatically extracting character patterns from pattern data of a graphic cell.
      SOLUTION: An electron beam drawing data producing method with an action of extracting the graphic cell in device pattern data by which a cell base design is carried out as the character patterns, comprises the steps of:removing overlapping pattern data contained in the graphic cell; generating a character pattern segment frame from a cell arrangement frame 10 contained in the graphic cell; assigning a graphic 21 in this segment frame to a pattern shot by CP system as the character patterns; making a graphic 22 outside the segment frame as non-character patterns; removing overlapping adjacent patterns to the non-character patterns; and assigning non-overlapping adjacent patterns to a pattern shot by VSB system.

    • 要解决的问题:通过从图形单元的图案数据自动提取字符图案,减少伴随字符图案校正工作的用户的加载而不引起任何双重曝光。 解决方案:一种电子束绘制数据产生方法,其特征在于包括以下步骤:移除包含在所述图形单元中的重叠图案数据, 图形单元格 从包含在图形单元中的单元布置框架10生成字符图案段帧; 将该段帧中的图形21分配给由CP系统拍摄的图案作为字符图案; 在片段外部形成图形22作为非字符图案; 将重叠的相邻图案移除到非字符图案; 并将非重叠的相邻图案分配给由VSB系统拍摄的图案。 版权所有(C)2005,JPO&NCIPI
