There are many variants of this 3D foams as its constituent materials can be derived from almost any nano to micro sized materials. Of the many types of these foams the most highly research would belong to the 3D-carbon and 3D-BN variants. The 3D-C variant is largely build up by graphene while the BN variant is made from 2D hexagonal BN. Both of these 3D foams are very similar in terms of their crystalline structure as well as their superior thermal properties but differ widely in their electrical and electronic characteristics. Here in this talk we will focus on some of the new applications that can be derived from these foams. Our focus would be largely on the use of the foams for thermal domains in its intrinsic form as well as its composite form. For its intrinsic use, we will demonstrate how our 3D-C and 3D-BN with high cross-plane thermal conductivity (62–86 Wm-1K-1) and excellent surface conformity could be used as high performance thermal interface materials (TIMs) with exceedingly high operational temperatures (exceeding 600 C). Besides materials characteristics, actual on-chip performance will also be showcased. On the compositional front, we will highlight how, through the integration of our foams with other matrix materials, these foams can be utilized for space protective applications.","PeriodicalId":418495,"journal":{"name":"2018 IEEE 2nd Electron Devices Technology and Manufacturing Conference (EDTM)","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114828233","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}

Voltage Ramp Stress (VRS) and Constant Voltage Stress (CVS) tests were performed at 25°C and 125°C to study the FEOL gate dielectric and device reliability such as gate dielectric breakdown voltage (VBD), Hot Carrier Injection (HCI), and Bias Temperature Instability (BTI). Apart from FEOL reliability study, special test structures were also designed to capture even a minor TSV impact on the lower metal and via levels of the BEOL stack. Time Dependent Dielectric Breakdown (TDDB), Electro migration (EM), and Stress Migration (SM) were performed to investigate any potential impact to BEOL due to TSV mechanical stress or Cu pumping effects. TSV KOZ impact on electrostatic discharge (ESD) protection devices was also performed. Our study with thick and thin TSV wafer showed no significant impact of TSV integration approach on FEOL, BEOL and ESD reliability.","PeriodicalId":418495,"journal":{"name":"2018 IEEE 2nd Electron Devices Technology and Manufacturing Conference (EDTM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114981268","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}

Electrical behaviors of PZT-based and Si:HfO2-based NC-FETs are investigated and discussed. In a PZT-based p-type NC-FET, a sub-thermal swing down to 20mV/dec is achieved due to the remarkable voltage gain of NC, reaching a maximum value of 10V/V. Nevertheless, the performance improvements with Si:Hf5O2 NC booster are significantly lower than PZT due to the coexistence of different phases and also high leakage current which can enormously reduce the enhancement by NC.","PeriodicalId":418495,"journal":{"name":"2018 IEEE 2nd Electron Devices Technology and Manufacturing Conference (EDTM)","volume":"2004 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125830810","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}
