Nano cluster devices announces new nano-patterning technologies

Christchurch, New Zealand | August 07, 2005

Two new technologies for fabricating tiny electronic devices have been unveiled by Christchurch, New Zealand, based Nano Cluster Devices Ltd.

The first technology is a new variation on the techniques used by the semiconductor industry to produce computer chips. René Reichel, a PhD student who played a key role in developing the techniques, said, “Our new technique eliminates one of the processing steps that is currently needed to do lithography.”

The new technology can be used to produce patterns in almost any shape, and has been demonstrated by fabricating a tiny map of New Zealand, as well as electronic devices more than 1000 times smaller than the thickness of a human hair. All of NCD’s technologies are based on the assembly of clusters, which are particles with dimensions of a few billionths of a metre.

The second technology is an improvement on stencilling techniques that are widely used in industry, but often suffer from problems where the stencils “clog.” “It’s a bit like spray painting through a stencil, except that we are spraying clusters and not paint,” says Dr Jim Partridge who was the lead researcher on both projects. “By controlling the conditions so that the clusters do not stick to the stencil, we have shown that we can eliminate clogging and make very narrow wires.”

“These are really significant developments,” says NCD Chief Scientist Dr Simon Brown. “These new technologies allow faster and easier patterning of nanodevices, and may provide significant economic and technical advantages over existing technologies used by the semiconductor industry.”

The new technologies were developed by Jim Partridge, René Reichel and David Mackenzie in the Department of Physics and Astronomy at the University of Canterbury on behalf of NCD. NCD has filed patent applications on the new technologies in addition to those for its previously announced methods of self-assembling clusters (or nanoparticles) into nanowires.

Nanotechnology is an emerging field widely seen as having as great an importance as biotechnology and information technology. Nanotechnology will have tremendous impacts in these fields as well as in electronics, medicine and many others. NCD’s self-assembled nanowires could also be used as the key components in transistors or as interconnects between devices on silicon chips. Nanowires therefore have the potential to enable much smaller and faster computers than those possible today.

NCD’s Dr Brown has recently been invited to present at the prestigious NanoCommerce / SEMI NanoForum in Chicago in early November. Last month, NCD’s nanowire technology was showcased to the international semiconductor industry, after selection by a panel of industry experts for the Technology Innovation Showcase (TIS) in conjunction with the SEMICON West conference in San Francisco in July.

About Nano Cluster Devices Ltd.:

Nano Cluster Devices Ltd was formed in early 2003 to commercialize a unique combination of top down and bottom up approaches to nano-technology. The key aspect of the technology is that nano-wires can be self-assembled between electrical contacts without the time consuming and expensive manipulation that typically hinders the production of nano-devices.

Nano Cluster Devices Limited has developed novel methods for taking clusters of atoms and forming them into electrically conducting wires. These wires are so small they can only be seen with the aid of an electron microscope. They have a wide range of applications in many of the world’s multi-billion dollar industries. A comprehensive Patent Portfolio has been established.
