A compact thermal model is introduced, incorporating the most advanced understanding of nanoscale heat conduction available. Novel device scaling is analyzed from a thermal point of view. We show device temperatures are very sensitive to the choice of drain and channel extension dimensions, and suggest a parameter design space which can help alleviate thermal problems. ITRS power guidelines below the 25 nm technology node should be revised if isothermal scaling of thin-body devices is desired.","PeriodicalId":344286,"journal":{"name":"IEEE International Electron Devices Meeting 2003","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127973586","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}

It is shown that the low-k film growth rate from the matrix monomer such as divinyl siloxane-benzocyclobutene (DVS-BCB) and the elastic modulus of the deposited films are enhanced by adding a deposition acceleration monomer and a reinforcement monomer, respectively, without increasing the k-value.

Based on dedicated simulations, it is shown that the maximum gain in on current achieved with steep profiles does not exceed 3%. Moreover, a suited analytical modeling indicates that the influence of the LA mostly resides in changing the effective channel length (Leff). Subsequently, the impact of the gate overlap is critically reviewed and actually appears to be mostly related to the analytical definition of the simulated device. Eventually, relying on a clear physical background, the analysis is carried out further to investigate the modulation of source injection properties in the framework of the backscattering theory and Monte Carlo (MC) simulations. We propose an additional injection effect that emerges at the source end potential barrier when the junction becomes very abrupt. This effect incorporated within the theory of Lundstrom enables further interpretation and understanding of the MC on-state current calculations.","PeriodicalId":344286,"journal":{"name":"IEEE International Electron Devices Meeting 2003","volume":"51 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121194460","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}
