Using a recent breakthrough in atomistic modeling, more than 100× reduction in simulation time was achieved using a tight binding mode-space approach. This enabled full-band transport simulation for a device with ~100,000 atoms, employing an accurate sp3s*SO (10 orbitals/atom) tight binding basis. At IOFF of 10 pA/μm, an optimized n-TFET with a pocket region is predicted to have ION of 46 and 196 μA/μm at VDD of 0.3, and 0.5 V, respectively. This achieves a better energy-delay product than its MOSFET counterpart. Through careful design, similar performance can be achieved for p- and n- TFETs.","PeriodicalId":441941,"journal":{"name":"2016 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124815455","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}

All vacuum spacer devices with low permittivity reduce fringing capacitance and improve performance. However, for gate-to-source/drain underlap InGaAs-OI FinFET, all vacuum spacer device degrades source/drain resistance (Rsd) and ON current (Ion), thus exhibiting slight improvement in inverter delay compared with the all nitride spacer device. Corner spacer design comprising of high-k and low-k composite spacer is proposed to optimize Rsd and capacitance, and hence improve delay. Various lengths and heights of corner spacer for InGaAs-OI FinFET with different underlap length and fin height aspect ratio are investigated to optimized performance. The optimized corner spacer design is: (a) the length of corner spacer (Lcorner) is approximately equal to underlap length (Lun), and (b) the height of corner spacer (Hcorner) is proportional to the sum of fin height (Hfin) and gate oxide thickness (Tox). Compared with the all vacuum spacer InGaAs-OI FinFET with Lun = 6 nm, the optimized corner spacer design exhibits 36% and 10% improvements in Ion and inverter delay, respectively.","PeriodicalId":441941,"journal":{"name":"2016 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132558299","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}
