Particle elimination efficiency is limited by suppression of device degradation and cleaning is invalid for the particles generated during etching and film formation. Particle reduction depends on particle characteristics, i.e. the sticking force and the chemical structure of the particles. Metallic contamination on wafers, dependent on a kind of solutions and the concentration in a solution, degrades TDDB characteristics and recombination lifetime. Although the lifetime degradation is a serious problem for ULSI, the damage by etching and by ion implantation causes the lifetime lowering rather than metallic contamination.","PeriodicalId":114928,"journal":{"name":"International Symposium on Semiconductor Manufacturing, Extended Abstracts of ISSM","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131821016","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}

These range from addressing market scenarios and factory performance at the strategic level to the performance of individual equipment at the tactical level, such as throughput, clustering and reliability. The modeling of individual equipment and process is an important link in the overall drive to comprehend and reduce cost factors at the factory level. This paper describes the application of analytical and computational modeling techniques used to optimize process and equipment design of furnace, chemical vapor deposition (CVD), rapid thermal processing (RTP), and plasma etch and deposition equipment.","PeriodicalId":114928,"journal":{"name":"International Symposium on Semiconductor Manufacturing, Extended Abstracts of ISSM","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114799041","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}
