With changing dielectric thickness due to downscaling of complementary metal oxide semiconductor (CMOS) technology as well as the shift from SiO2 to other high permittivity dielectric materials, there is a noteworthy change in the physics of failure and the statistical trend of soft, progressive and hard breakdown in oxide films. This study presents a brief summary comparing the physical mechanisms of breakdown and associated stochastics of the failure time distribution in SiO2 and high-κ (HfO2. It is clearly evident that there is a continuous need for more research into oxide breakdown, given the shift towards 2D layered dielectrics such as hexagonal boron nitride in the near future, with markedly different breakdown dynamics.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130484248","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}

The dual-mass resonant structure that comprises of a primary mass and an accessory mass is structured on silicon-on-insulator (SOI) wafer by double-sided deep reactive-ion etching (DRIE). Unlike previous 2DOF harvesters, the induction coil is only patterned on the primary mass for energy conversion. By carefully adjusting the weight of accessory mass, the first two resonances of the primary mass can be tuned close to each other while maintain comparable magnitudes. Therefore, both resonances could contribute to energy harvesting that make the system more efficient and adaptive in frequency-variant vibrational circumstances. With the current prototype, two close resonances with a frequency ratio of only 1.19 and comparable peaks are achieved, providing good validation for the modeling results.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114922629","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}

The paper shares an innovative fluxless FC bonding technique known as solid liquid interdiffusion by compressive force (SLICF) for MEMS packaging.The instantaneous SLICF bonding utilizes a mechanical force to break the Sn oxide layer and allows the submerged body to interact with fresh molten solders to form bonds through solid liquid inter-diffusion.

This paper reports the development of resistive graphene-based MEMS pressure sensor integrated with interdigitated electrode. These interdigitated electrode structure act as pressure magnifying structure as well as reducing the output non-linearity. A COMSOL simulation was carried out for design optimization of the resistive pressure sensor. In this study, the effect of optimization of the spacing between the Al electrodes is presented to improve the performance of graphene-based pressure sensors at room temperature. Three different spacing distances of 10, 20 and 40 μ m were used as the experimental parameters. The increased spacing could affect in increasing tensile strain on graphene and increased defect generation at the grain boundaries. Therefore, the pressure sensor response could also be improved by increasing the spacing of the interdigitated electrode.","PeriodicalId":310101,"journal":{"name":"2018 IEEE 8th International Nanoelectronics Conferences (INEC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125670175","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}
