Nano-chip is not there yet ”

There is a yawning gap between the great inventions in the field of nanoelectronics that are currently being made by science and complex silicon chips as they are currently used, suggests a Dutch professor of chip design.

Bram Nauta Bram Nauta, Professor of Integrated Circuit Design at the University of Twente, does not believe in the idea that there are many new electronics invented by starting at the nanoscale and to create. Complex nano-chips via that route In the current chip manufacturing is becoming switched to a smaller process. “But soon, the bottom-up, then I hear,” said Nauta in a speech he at the University of Twente will Friday hold . “You take the smallest building block, a molecule, and makes a kind of transistor. So you start small and build from getting bigger.”

According to Nauta be there achieved good results with it, and he is convinced that some of these inventions end up in future chips. “But at the moment there is still a large gap yawns between many inventions from the nano-science and hugely complex chips that are now in the shops,” said the professor. “Personally, I do not think we are going to invent a whole new electronics,” he continued.

“Because imagine, I am able to do that has about the same effect as a silicon transistor, so a molecule can enable and strengthen. I show that the molecule works. Magnificent,” Nauta said, “but put it once against the enormous complexity of the chip of the iPhone. Therein the billions of transistors are connected by highways, sometimes eight or nine layers one above the other. How are you going to do with those molecules How do you guarantee that it works? ”

The professor is also convinced that the ‘top-down express train “in the chip development be some rumbles. “That’s not a done deal, that’s all nanotechnology. What is now on sale in the shop are transistors of 40 to 50 atoms long and a few atoms thick.”
