For this notch length, no degradation in SCE and at the same time a slight improvement in Gmsat was measured in comparison with standard transistors. In addition, a reduction of poly-depletion due to a better activation of dopants in SiGe in both NMOS and PMOS gates has been measured.","PeriodicalId":345274,"journal":{"name":"31st European Solid-State Device Research Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125925373","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}

In the case of MOS transistors, it has been widely reported that mismatch is related to the random fluctuations of channel dopant number [1] [2] [3].
