Substrate engineering [1] has enabled the industry to overcome many of the limitations encountered by traditional scaling. As a result, device architecture and engineered substrates have become strongly coupled, a coupling that is growing stronger as the IC industry moves to the 32 nm technology node and beyond. Substrate engineering started in earnest with the industry transition to SOI wafers...

Abstract In this work, we investigate and analyze the impact of gate tunneling on dynamic behaviors of partially depleted SOI CMOS with the aid of the physically accurate BSIMPD model. We examine in particular the impact of gate tunneling on the history dependence of inverter delays. The examination reveals key requirements for capturing the history effect in SPICE modeling. This study suggests...

In this article, a novel concept is introduced to improve the Radio Frequency (RF) linearity of Partially-Depleted (PD) Silicon-On-Insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free cir...

The coupling between the spin and orbital degrees of freedom of photons is usually very weak, but recent studies have shown that this spin-orbit interaction (SOI) can be easily detected in metal structures. Here we show how the SOI of light is enhanced in plasmonic metal nanostructures, explore the underlying mechanism for this effect, and further demonstrate how it could potentially be harness...

Hand, foot and mouth disease (HFMD) was an emerging viral infectious disease in recent years in Shenzhen. The underlying risk factors have not yet been systematically examined. This study analyzed the short-term effect of El Niño-Southern Oscillation on pediatric HFMD in Shenzhen, China. Daily count of HFMD among children aged below 15 years old, Southern Oscillation Index (SOI), and weather va...

in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...
