    • A pattern verification method includes preparing a desired pattern and a mask pattern forming the desired pattern on a substrate, defining at least one evaluation point on an edge of the desired pattern, defining at least one process parameter to compute the transferred/formed pattern, defining a reference value and a variable range for each of the process parameters, and computing a positional displacement for each first points corresponding to the evaluation point, first points computed using correction mask pattern and a plurality of combinations of parameter values obtained by varying the process parameters within the variable range or within the respective variable ranges. The positional displacement is a displacement between first point and the evaluation point. The method further includes computing a statistics of the positional displacements for each of the evaluation points, and outputting information modifying the mask pattern according to the statistics.
    • 模式验证方法包括在衬底上制备期望图案和形成期望图案的掩模图案,在期望图案的边缘上限定至少一个评估点,限定至少一个过程参数以计算所转移/形成的图案,定义 针对每个处理参数的参考值和可变范围,并且计算与评估点相对应的每个第一点的位置偏移,使用校正掩模图案计算的第一点和通过改变处理参数获得的参数值的多个组合 在可变范围内或在相应的可变范围内。 位置偏移是第一点与评价点之间的位移。 该方法还包括计算每个评估点的位置偏移的统计量,并根据统计信息输出修改掩模图案的信息。
