Some scattered particles collide with a wafer at a high velocity, which damage fine patterns of the photoresist on a wafer. Particle contamination can be reduced by supplying carrier gas to form down-flow, when etching plasma is not discharged. During plasma discharge, the number of particles that fall on the wafer decreases, because particles are trapped near the plasma-sheath boundary. We found that down-flow particle control reduces particle contamination by 90% through etching including wafer transfer.","PeriodicalId":184890,"journal":{"name":"2008 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002177","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}

KLA-Tencor's patented Process Window Qualification (PWQ) methodology has been used for this purpose in various fabs. PWQ methodology has three key advantages (a) PWQ Layout - to obtain the best sensitivity (b) Design Based Binning - for pattern repeater analysis (c) Intelligent sampling - for the best DOI sampling rate. This paper evaluates two different analysis stratagies for SEM review sampling successfully deployed at Inotera Memories, Inc. We propose a new approach combining the location repeater and pattern repeaters. Based on a recent case study the new sampling flow reduces the data analysis and sampling time from 6 hours to 1.5 hour maintaining maximum DOI sample rate.","PeriodicalId":184890,"journal":{"name":"2008 International Symposium on Semiconductor Manufacturing (ISSM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128034908","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}
