CITRIS Research Exchange - Minimal Manufacturing through Ink-jet Technology

September 12, 2007: 12:00pm - 1:00pm
Location: 290 Hearst Memorial Mining Building, the Maria & Dado Banatao Conference Room, UC Berkeley

Please join us for a talk by Kazuhiro Murata, Senior Scientist at the National Institute of Advanced Industrial Science and Technology (AIST) on "Minimal Manufacturing through Ink-jet technology", Sept. 12 at noon in 290 HMMB, UC Berkeley.

Part of the CITRIS Research Exchange at UC Berkeley. The complete schedule for the fall semester is online at RE-Fall2007. Sponsored by Infineon Technologies.

Abstract:

“Minimal manufacturing” is our fundamental research concept that, through the utilization of nanotechnology, overcomes the three technological issues that in the past have been in conflict with each other—“resource conservation and energy conservation,” new functions and high performance functions” and “high productivity and low cost.” Applying inkjet technology to processes in the electronics industry is one link in our work towards this goal. We have developed a micron accurate inkjet system that allows the arrangement of dots with a minimum size of less than one micron. Using a nano metal paste as an ink material, we achieved the direct printing of metallic wires of only a few micrometers in width without any pre-patterning treatment of the substrate. Direct forming of three-dimensional structures anywhere on a substrate has also been demonstrated, made possible by taking advantage of the rapid drying of the small volume droplets printed. The process is simple and the entire setup can be carried out on a desktop, in an ambient environment, and at room temperature. By combining this method with advanced material and ink processing, electronic devices may eventually be manufactured not by a large factory but by small-scale equipment that can sit on a desktop.

Biography:

Dr. Kazuhiro Murata received the Ph.D. degree in materials science from the University of Tohoku, Japan, in 1994. From 1994, he joined the electro-technical laboratory at AIST and worked on basic physics of conducting polymer and organic thin films. From 1999 to 2000, he worked on organic electronics in the Cavendish laboratory of Cambridge University as a Visiting Scholar. Since 2002, he has been team leader of collaborative research team of super inkjet technology. He has received awards such as Nanotech award 2002 and Best Paper of ICEP in 2005. He is also founder SIJ Technology. Inc.
