Then, BL and MR are studied and the improvement of SB-NWTs is investigated. It is found that the SS of SB-NWTs cannot be superior to that of SNWTs and unexpected DIBL/FoM degradation may be induced. In addition, Rlin-SB-NWTs is found to be always worse than Rlin-SNWTs if LSDE of SNWTs is designed to be adequately short (e.g. LSDE≪10nm).

However, demonstrations of exceptional III–V performance required device footprints on the µm-scale despite nm-scale gate lengths, in order to avoid source/drain shorting during contact alloying. The scaling of III–V FETs is severely limited by the unacceptably large lateral diffusion of the multilayer alloyed structures typically used for ohmic contacts [4]. In our recent work, we introduced a novel non-alloyed, highly scalable contact structure through the use of Al as a low workfunction metal on an unpinned Fermi level [5]. We use GaAs as a baseline III–V material, where the developed contact techniques can be extended to InGaAs and InSb, materials which are more technologically important [6]. In this work, we explain in detail the unpinning mechanisms and the rationale for the material selection. We demonstrate the same method can be applied to a variety of metals, Y, Er, Al, Ti, W, and Pt, providing much flexibility in the design of an ideal source/drain contact for III–V HEMTs/MOSFETs and Schottky Barrier FETs.","PeriodicalId":309622,"journal":{"name":"2009 International Symposium on VLSI Technology, Systems, and Applications","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122867907","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}
