In order to meet the demand of coma measurement accuracy of lithographic tool projection lens,a novel method for measuring coma based on fine overlay error metrology marks is proposed.
为了满足光刻机投影物镜彗差测量精度的要求,提出一种基于套刻误差测试标记的彗差检测技术,分析了彗差对套刻误差测试标记空间像的影响,详细叙述了该技术的测量原理,并利用PROLITH光刻仿真软件对不同数值孔径与部分相干因子设置下套刻误差相对于彗差的灵敏度系数进行了仿真实验。
