研究并讨论了下一代光刻的核心技术之一-激光等离子体极紫外光刻光源。简要介绍了欧美和日本等国极紫外光刻技术的发展概况，分析了新兴的下一代13.5 nm极紫外光刻光源的现状，特别讨论了国内外激光等离子体极紫外光刻光源的现状，指出目前其存在的主要问题是如何提高光源的转化效率和减少光源的碎屑。文中同时概述了6.x nm(6.5~6.7 nm)极紫外光刻光源的最新研究工作。最后，介绍了作者所在研究小组近年来在极紫外光源和极紫外光刻掩模缺陷检测方面开展的研究工作。

Laser-produced Plasma(LPP) Extreme Ultraviolet Lithography(EUVL) light source, one of the core technologies of next generation lithography, is discussed. A brief review to the development situation of lithography technology in Europe, America and Japan is given. Being a newly arisen research direction, the status of next generation 13.5 nm EUVL source is analyzed, and especially the research on EUVL source based upon LPP at home and abroad is described and analyzed in detail. It points out that the main problems for the EUVL are how to improve the conversion efficiency of EUV light and how to reduce the light debris. Furthermore, the latest research status on the EUVL source at 6.7 nm is also presented. Finally, it introduces the research work of the author′s group on EUVL light sources and the detection of mask defect for EUVL.
