| 中文摘要: |
| 在17~19 nm波段,利用直流磁控溅射技术将Al(1%wtSi)/ Zr多层膜镀制在掺氟的二氧化硅基底上,基于原子力显微镜对不同膜对数(N=10,40,60,80)表面粗糙度的测量结果,将多层膜的生长模型应用于实际结果中,对表面均方根粗糙度随着膜对数的变化进行了深入的分析,并对Stearns粗糙度动态生长理论的适用条件作了补充性讨论。 |
| 英文摘要: |
| Al (1%wtSi)/Zr multilayers were fabricated by DC sputtering techniques on doped fluoride glass substrates for 17~19 nm extreme ultraviolet radiation. The surface roughness of the multilayers with variable layer pairs (N=10, 40, 60 and 80) were measured by an atomic force microscopy. Their reflectivities were measured and fitted based on multilayer growing method improved by Stearns. Experiment and analysis present that the interface roughness were variable with the growing of Al/Zr multilayers and coincide the Stearns′ method as N≤40. |
