We attribute this to electric-field-induced migration of fluorine ions (F−) introduced during the RIE gate recess process. F− is known to passivate Si donors in InAlAs. In our device structure, an n-InAlAs ledge facilitates the link from the contacts to the intrinsic device. We use secondary ion mass spectroscopy (SIMS) to independently confirm that our process leads to F pile up at the n-InAlAs layer. Transmission line model (TLM) structures confirm F−-induced donor passivation. The understanding derived has lead us to redesign our InGaAs MOSFETs by eliminating n-InAlAs layers and instead use an n-InP ledge. The new device design not only exhibits greatly improved electrical stability but also record performance.","PeriodicalId":186544,"journal":{"name":"2016 IEEE International Electron Devices Meeting (IEDM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115080815","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}

A planar double-gate ultra-thin-body (DG-UTB), a triple-gate FinFET, and a gate-all-around nanowire (NW) transistor have been designed according to the ITRS specifications for two technology nodes with physical gate lengths of Lg=15 nm and 10.4 nm. A thorough performance comparison of digital and analog figures of merit at these nodes reveals that for Lg=15 nm, the performance of planar and 3-D architectures is comparable. At LG=10.4 nm, the III-V NW promises the highest performance, especially when lowering the supply voltage from 0.59 V to 0.50 V. It also significantly outperforms its strained silicon counterpart. Finally, the effects of series resistance combined with interface traps, surface roughness, alloy scattering, and electron-phonon interactions have been found to deteriorate the III-V ballistic ON-current by 50–60%.","PeriodicalId":186544,"journal":{"name":"2016 IEEE International Electron Devices Meeting (IEDM)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121792164","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}

As-fabricated end-bonded Ni contacts serve as robust p-type contacts to CNTs and perform better than standard Pd side-bonded contacts at scaled dimensions. In addition, stable NFETs are converted from PFETs using Al2O3 as an n-type physicochemical doping layer. CMOS inverters are further built with end-bonded contacts for both PFETs and NFETs, featuring the smallest contact size thus far for CNT inverters. These new findings could pave the way to realizing CNT-based scalable CMOS technology.","PeriodicalId":186544,"journal":{"name":"2016 IEEE International Electron Devices Meeting (IEDM)","volume":"52 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122107985","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}

Fully metallic source and drain (MSD) process is one of the most promising solutions but it often suffers from intolerant junction leakage in bulk FETs. In this paper, fully MSD process on fin-on-insulator (FOI) FinFET is investigated extensively for the first time. By forming fully Ni(Pt) silicide on physically isolated fins, about 90% reduction in contacted resistivities (Rcs) and 55% reduction in sheet resistances (Rss) are achieved without obvious junction leakage degradation. As a consequence, Ion of transistor, with gate length (Lg) of 20nm, is increased 30 times, up to 547μA/μm for NMOS and 324 μA/μm for PMOS, respectively. Excellent controls of SCE and channel leakage with 47% DIBL, 32% SS and 2.5% device leakages reductions over the counterpart of conventional bulk FinFETs are also obtained. Meanwhile, the fully MSD process induces clear tensile stress into narrow fin-channel, resulting in enhanced electron mobility in NMOS. A further improvement in PMOS drive ability (486μA/μm) by using Schottky barrier source and drain (SBSD) technology is also explored.","PeriodicalId":186544,"journal":{"name":"2016 IEEE International Electron Devices Meeting (IEDM)","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123785726","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}
