Also an EOT of 0.39nm with a dielectric thickness of 2.4nm requires an average dielectric constant of the gate stack of 25. This would require a crystalline dielectric without interfacial SiO2 layer. While this is not unheard of, it is typically not possible to achieve sufficient channel mobility in a gate stack like that.
A leakage current of 1e-12 A/cm² is physically impossible with an insulator thickness of 2.4nm. It would required a material with an unrealistically high band gap.
There appear to be factual mistakes in the article.
CYI-what are you talking about?
Being able to use a thinner EOT helps with gate control (short channel effects) as well as reducing gate leakage.
Granted, this article is not impressive with an EOT of 390A but I suggest you don't mislead others with a lopsided view on gate dielectrics.
While it is true that high-k materials will virtually eliminate gate leakage, the use of these materials will not significantly reduce subthreshold leakage which will continue to account for a significant percentage of a chip's total power consumption.
At 90nm, leakage power accounts for about 30% of a chip's total power and almost all of the leakage power is due to subthreshold leakage, as opposed to gate leakage.
At 65nm, over 50% of a chip's power is due to leakage and about 60-70% is due to subthreshold leakage.
At 45nm, gate leakage would have grown to overtake subthreshold leakage. With the use of high-k materials, the threat of gate leakage is tamed.
However, subthreshold leakage will continue to be a critical parametric yield-limiting factor at 45nm and beyond.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
