Silicon transistors will encounter pressure from nanoelectronics

19.11.2002


The future of nanoelectronics looks promising. Built with nanotubes and various self-assembling molecular structures, this technology may revolutionize the electronic world by replacing the silicon transistor in approximately ten years.



Chemically synthesized nano building blocks are expected to replace semiconductor logic and memory devices and target niche applications over the next decade.

"In 20 to 50 years, we will likely see wide-ranging use of self-assembly," says Technical Insights Director of Research Leo O’Connor.


Extreme ultraviolet (EUV) lithography is currently favored by chipmakers, and some companies are expected to use EUV to replace 157 nm scanners in the second half of the decade. Japanese electronic companies have joined forces to develop low-energy electron-beam proximity projection lithography.

Currently, chipmakers are working to make the 157 nm lithography technology operational by 2003. In doing so, they have come up against many obstacles such as the availability of calcium fluoride for lens manufacturing and contamination of optical elements.

Researchers are working to address these difficulties. Recently, supporters of various forms of next-generation lithography reported progress on 157 nm optical, projection e-beam lithography and EUV lithography. Although expensive, EUV scanners will work at the 13.5 nm wavelength and take manufacturers over several process generations.

Although chip technology plays a crucial role in the semiconductor industry, researchers believe that it is only a matter of time before the switch from lithographed silicon chips to self-assembled nanoelectronics takes place.

In anticipation of the eventual change, researchers at various universities are experimenting with different technologies. At Delft University in the Netherlands, for example, researchers have built basic logic circuits with carbon nanotubes, while at Harvard University a group of researchers used indium phosphide nanowires to build the same types of devices.

Molecular self-assembly is not without its share of problems. Despite challenges, it seems clear that nanotechnology will have a profound impact on the future development of many sectors, particularly that of electronics, which demands technologies that enable faster processing of data at lower costs.

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
