The resist height reduces to maintain the aspect ratio below 2:1 which is critical factor for the prevention of the resist collapse. This leads to huge challenges to minimize the shrinkage of resist during the scanning electron microscope (SEM) measurement. Accurate and precise metrology of chemically amplified resist (CAR) type EUV photoresist processed pattern utilizing classical beam energy for lithography pattern such as 500V is great challenging as electron beam exposure of 1st measurement already fully shrunk the pattern. Moreover, occurrence of carbonization along with shrinkage hinders finding best conditions for not only metrology optimization but also minimized process impact. In this work, we evaluated the magnitude of shrinkage of CAR type EUV photoresists with several approaches including 0th and 1st shrinkage estimation utilizing line & space pattern and contact hole pattern as a function of landing energy dose and static/dynamic repeatability method to distinguish behaviors of shrinkage and carbonization by controlling interaction time of photoresist to its environment. One approach to trace minimized 0th shrinkage and metrology uncertainty in lithography process is utilizing 1st shrinkage (1st CD – 2nd CD) analysis together with plotting absolute value of the 1st CD as a function of dose. The other approach to trace optimization condition was comparing exposed area with electron beam and non-exposed area achieved by comparing litho/etch consecutive process on the same area. Furthermore, model fits, a simulation study were also performed.","PeriodicalId":393709,"journal":{"name":"Metrology, Inspection, and Process Control XXXVII","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124215824","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}
