By applying the RF testing skill for the proposed SOI test patterns, we can eliminate properly the parasitic elements due to the co-existence opposite poly gate type the SOI T-shape body-tied (BT) device and accurately characterize and model the SOI FB Igb and Cgg behaviors. Impact on the history effect was analyzed by BSIMSOI4.0 model. History effect analysis with high pulse and low pulse width was shown. Improvement of more than 3% simulation accuracy for history effect was also demonstrated.","PeriodicalId":175818,"journal":{"name":"2009 IEEE International Conference on Microelectronic Test Structures","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124001161","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}
