为满足45 nm及其以下节点光刻技术对照明系统的需求,将深紫外光刻照明系统的光束整形单元所采用的微反射镜阵列(MMA)作为关键器件,以实现满足光源-掩模联合优化(SMO)技术需求的任意照明光源。根据MMA结构参数和加工制造调整特性,分析MMA角度误差类型。在此基础上,利用蒙特卡罗公差分析法模拟实际加工制造调整的过程,通过分析微反射镜角度误差对曝光结果的影响,制定了满足曝光要求的角度公差。结果显示,当MMA在正交方向上的角度调整公差和加工角度公差分别在(±0.04°,±0.06°)、(±0.04°,±0.0

高重复频率干扰激光器被激光导引头精确探测是高重复频率有效干扰的必要条件,因此基于激光导引头探测性能研究高重复频率干扰激光器至关重要。采用计算分析的方法研究导引头虚警概率和探测概率,得出:当阈噪比TNR为3.5时,虚警概率Pf约为0.02%;当阈噪比TNR为3.5且被检测信号在导引头入瞳处的功率密度为导引头探测器门限值的1.9倍时,探测概率Pp约为99.92%。基于探测概率研究高重复频率干扰激光器的激光导引头探测概率Pp与高重复频率干扰激光器参数(平均功率P1、脉冲发射频率f、脉冲宽度τ)、激光导引头参数(
