In the context of SPICE MOSFET model parameter shifts, the parameter extraction methodology utilised contributes to the “ease” in which parameter degradation trends can be modelled. This paper will demonstrate that direct parameter extraction techniques produce more monotonic parameter degradation trends than conventional optimisation techniques. In addition, a novel approach for the modelling of the evolution of directly-extracted parameters during hot-carrier stress is presented. Finally, a statistical validation, comparing measured and simulated degraded ring oscillator data, is presented.","PeriodicalId":354721,"journal":{"name":"30th European Solid-State Device Research Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115147699","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}

Moreover, due to the front-side RF ground contact, compatibility to conventional packaging is maintained.
