IBM stakes claim to nano-scale printer
Tiny printing from Big Blue
Researchers
from IBM and ETH Zurich have developed a method for placing minuscule
particles on a precise location.The new technique delivers a printing
resolution equivalent to 100,000 dots per inch (dpi). Current printers
top out around 1,200-1,500 dpi.The discovery could eventually allow for
printing technology that could be used to create nano-scale wires or
ultra-small lenses for use in optical chips.Big Blue admitted
that the technology is still years away from any commercial
applications, but the company is hopeful that the breakthrough will
help accelerate the development of nanotechnology.”This method opens up
new ways to precisely and efficiently position various kinds of
nanoparticles on different surfaces,” said IBM Zurich researcher Heiko
Wolf.”[This is] a prerequisite for exploiting the unique properties of
such nanoparticles and for making their use economically feasible.”As
current methods of constructing chips approach their limits,
researchers have looked for new methods to continue shrinking chip
sizes. IBM’s latest discovery could help in that process.
