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.

One is the growth of ultra-thin and high-quality gate dielectrics (preferably high-k) on top of the pristine surfaces of 2D semiconductors, which is a fundamentally difficult task. The other involves formation of ultra-short channel/gate using advanced lithography techniques, which are, however, usually expensive and/or of low yield. Using synthesized ultra-thin core/shell nanowire to gate the 2D semiconductors could be a promising approach, which not only facilitates a lithography-free ultra-short channel formation with relative ease, but also avoids the direct growth of dielectrics on 2D materials, which can help preserve the pristine nature of the 2D channel and its outstanding properties. In this work, aided by rigorous quantum simulations, we attempt to understand and optimize this nonconventional FET structure, guided by a prototype demonstration of this device. It is found that this unique FET structure offers 2D semiconductors a promising platform, in terms of manufacturability and device performance, for next-generation CMOS technology.","PeriodicalId":186544,"journal":{"name":"2016 IEEE International Electron Devices Meeting (IEDM)","volume":"39 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":"116804663","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 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.
