cluster devices announces new nano-patterning
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.
Map of New Zealand produced using NCD's No-Liftoff
Lithography TM technique. About 100,000 of these
maps would fit on the head of a pin.

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
“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.
