The High-NA EUV scanner will have an NA of 0.55 and anamorphic optics to keep the angles on mask level compatible with current masks. However, for selected use-cases increased Mask-3D effects are observed. \u0000In this presentation, we will show the root-cause of these enhanced M3D effects for High-NA EUV and the role of the mask multilayer, as well as how to improve it. We will also show some first experimental results of an ion beam deposited RuSi test sample.","PeriodicalId":106300,"journal":{"name":"Extreme Ultraviolet Lithography 2020","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132157293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
