In this report, a large SSD array with approximately 2,000 SSDs connected in parallel within the fingers of an interdigital structure was coupled with a printed-circuit-board- (PCB-) based wideband patch antenna, operating in the radio-frequency (RF) region. Such a large array was realized in a single lithography step without the need for interconnection layers. This allows for a simple, low-cost and reproducible fabrication process. Despite of the large impedance mismatch between the SSD array and the PCB-based antenna, the device was able to detect RF signals transmitted using a network analyzer via another patch antenna at distance of approximately 70 cm from it, at 2.45 GHz. The estimated room-temperature extrinsic voltage responsivity of the device and its noise-equivalent power, measured at 5 cm away from the transmitted RF signals and at zero bias, were 10 mV/mW and 1.2 nW/Hz1/2, respectively. The results have shown that the SSDs can be utilized in many RF applications at low cost.","PeriodicalId":346255,"journal":{"name":"RSM 2013 IEEE Regional Symposium on Micro and Nanoelectronics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127797393","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}

It is found that the material density and air-particle permittivity have the impact on the wave absorption of the material. The result shows that all three agricultural wastes are capable to absorb electromagnetic signal. The average dielectric constant for solid pulverized agricultural waste are 3.49, 4.06 and 3.31 for empty fruit bunch, oil palm frond and rice husk respectively. Furthermore, at of 15.0 GHz, the solid pulverized empty fruit bunch, oil palm frond and rice husk indicate the highest loss tangent with value of 0.2201, 0.2579 and 0.2218 respectively which contributed from the loss factor of the material complex permittivity.","PeriodicalId":346255,"journal":{"name":"RSM 2013 IEEE Regional Symposium on Micro and Nanoelectronics","volume":"9 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132405527","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}

Further improvement can be achieved when the device incorporated with thin buried oxide (BOX) since it allows suppression of fringing electric fields through the BOX thus improving front-gate-to-channel controllability and reducing DIBL. Thin BOX is also suitable for emulation of double-gate (implementing back-gate biasing) schemes used for tuning device characteristics. Thus, in this paper, from the advantages of double gate transistor, we investigate by using ATLAS 2D-simulations the emulation of double gate transistor with bottom contact (underneath the substrate) and top contact (from the top through the silicon and BOX) for both digital and analog/RF figures of merit in ultra-thin body and thin buried oxide (UTBB) SOI MOSFETs.
