How Will Nano Change the World?

Another nano video contest seeks to answer how nano will change the world

Thus is posed the question for the new video contest put on by the American Chemical Society. In the first contest, the question was simply “What is Nano?” and it turned out that question was best answered with puppets in full-throated song.

I enjoy watching videos as much as the next guy, but I have not quite figured out what purpose these videos are supposed to serve other than to compete in a contest. Are the editors of the ACS’ Chemical & Engineering News supposed to become informed of how nanotechnology is going to impact the world in a way that they hadn’t considered before? Are these videos supposed to become teaching tools for pre-schoolers as in the case with the puppet video?

I am entertained but I don’t get the purpose, or maybe there isn’t one.

3D-Stacked CMOS Takes Moore’s Law to New Heights

When transistors can’t get any smaller, the only direction is up

Perhaps the most far-reaching technological achievement over the last 50 years has been the steady march toward ever smaller transistors, fitting them more tightly together, and reducing their power consumption. And yet, ever since the two of us started our careers at Intel more than 20 years ago, we’ve been hearing the alarms that the descent into the infinitesimal was about to end. Yet year after year, brilliant new innovations continue to propel the semiconductor industry further.

Along this journey, we engineers had to change the transistor’s architecture as we continued to scale down area and power consumption while boosting performance. The “planar” transistor designs that took us through the last half of the 20th century gave way to 3D fin-shaped devices by the first half of the 2010s. Now, these too have an end date in sight, with a new gate-all-around (GAA) structure rolling into production soon. But we have to look even further ahead because our ability to scale down even this new transistor architecture, which we call RibbonFET, has its limits.
