Therefore, drivability enhancement is performed for damascene-gate nFETs with narrow channel width. High-drive current of 1430 uA/um at Ioff = 100 nA/um, Vdd = 1.0 V and the channel width of 0.3 um is achieved by the stress enhancement effects of the damascene-gate technology.","PeriodicalId":309622,"journal":{"name":"2009 International Symposium on VLSI Technology, Systems, and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127470388","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}

The thin BOX facilitates an effective modulation of ring characteristics with small (1–2V) independent backgate voltages. Leakage current per stage can be reduced by more than 100× with 30% increase of inverter delay. In addition, the inverter delay can be improved by 15% with 2× increase of the stand-by current.
