Oxide thickness scaling is performed to improve the on-state/off-state performance and Gm is further improved to 1.3 mS/µm. HBr pre-cleaning, retro-grade structure and halo-implantation processes are first time introduced into III-V MOSFETs to steadily improve high-k/InGaAs interface quality and on-state/off-state performance of the devices. We have also demonstrated the first well-behaved inversion-mode InGaAs FinFET with ALD Al2O3 as gate dielectric using novel damage-free etching techniques. Detailed analysis of SS, DIBL and VT roll-off are carried out on FinFETs with Lch down to 100 nm and WFin down to 40 nm. The short-channel effect (SCE) of planar InGaAs MOSFETs is greatly improved by the 3D structure design. The result confirms that the newly developed dry/wet etching process produces damage-free InGaAs sidewalls and the high-k/3D InGaAs interface is comparable to the 2D case. Finally, ultra-shallow doping for VT adjustment in deep submicron InGaAs MOSFETs using sulfur monolayers is demonstrated. This brings new potential solution to ultra-shallow junction formation for the further scaling of III-V MOSFETs.","PeriodicalId":197102,"journal":{"name":"2010 22nd International Conference on Indium Phosphide and Related Materials (IPRM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128292426","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}
