New technique producing small things in large quantities
Date:9/5/2007

HOUSTON, September 4, 2007 Although relatively new to the market, liquid crystal display (LCD) televisions may soon be obsolete, thanks to a new technique created by University of Houston professors.

Vincent Donnelly, Demetre Economou and Paul Ruchhoeft, all of the Cullen College of Engineering, have developed a technique that allows nanotech devices to be mass-produced, which could move the television industry away from the LCD display to the superior field emission display (FED). FEDs use a large array of carbon nanotubes the most efficient emitters known to create a higher resolution picture than an LCD.

The nanotech fabrication technique that can mass produce an ordered array of carbon nanotubes and make FEDs happen promises to remove some of the largest practical barriers to mass-producing nanotech devices, Economou said.

Dubbed nanopantography, the method uses standard photolithography to selectively remove parts of a thin film and etching to create arrays of ion-focusing micro-lenses small round holes through a metal structure on a substrate, such as a silicon wafer.

These lenses act as focusing elements, Donnelly said. They focus the beamlets to fabricate a hole 100 times smaller than the lens size.

A beam of ions is then directed at the substrate. When the wafer is tilted, the desired pattern is replicated simultaneously in billions of many closely spaced holes over an area, limited only by the size of the ion beam.

The nanostructures that you can form out of that focusing can be written simultaneously over the whole wafer in predetermined positions, Economou said. Without our technique, nanotech devices can be made with electron-beam writing or with a scanning tunneling microscope. However, the throughput, or fabrication speed, is extremely slow and is not suitable for mass production or for producing nanostructures of any desired shape and material.

With the right ions and gaseous elements, the nanotech fabricatio
