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。
It is shown that the symmetry of the spectral response and the coupling efficiency will be deteriorated when the coma appears during the diffraction and imaging.
最终证明彗差会造成谱形失称 ,明显降低耦合效率 ;而球差则会明显地增加串扰 。
