9nm IBM nanotube transistors may outrace silicon

Nanotube transistors hit new record

IBM researchers have published results for a new nine-nanometer nanotube transistor that could redefine processors in the future. The carbon-based element is the first below 10 nanometers and is much more efficient than the best current silicon-based transistors. Because of the size and material, it can use considerably less power and takes on more of a current to improve the reliability.

To get to the smaller size, researchers used an extra-thin insulator and a two-part process to bring in the electrical gates while preserving the fragile structure. Challenges still exist, such as improving the production process for the nanotubes to avoid shorts as well as creating a method to scale the placement up to processor-size levels.

As with most research, the 9nm technology is still likely years away from the market. IBM's role as a semiconductor giant may see its technique reach the mainstream when ready. [via MIT Technology Review]

    fed with could bullcrap technologies

    Instead of publishing PR stunts with technologies that "can", "may", "could", "would", change the world, these companies have to start creating technologies that use verbs in the present participle: is changing, is doing, is creating.

    Do we even have an estimate of how long it will take to build an actual chip with this? If it takes until 2020 to make the equivalent of what we have now, then "day late/dollar short" won't be the half of it.

    Looking forward to it

    To Lunar Moon (buried comment): Everything is a "could" or "may" before it is an "is" or "will". Look back at the history of stories about transistors, lasers,etc. Personally, I thought the article was sufficiently informative to merit reading. And, 2020 isn't that far away.
