Printed Devices and Large Area Interconnect Technologies for New Electronics

Printed-electronics is a set of printing methods used to create　electrical devices with large area, and three-dimensional interconnection. Printed-electronics is expected to facilitate widespread very low-cost, volume and performance electronics for applications such as flexible displays, concomitant formation of sensors and transistors, smart labels, furthermore active clothing. This Seminar focuses several kinds of advanced and unique materials and process technologies for realizing advanced printed-electronics.

概要　：The Ag nanoparticles are coated with an alkylamine dispersant. This alkylamine dispersant can be removed from Ag nanoparticle lines simply by washing in methanol for a few seconds. Immediately after the washing treatment, sintering of nanoparticles begins, even at room temperature. The other ink is based on the new chemical, β-ketocarboxylate Ag, which decomposes at low temperature [12]. The decomposition temperature can be designed by changing its substituents in the range 100 ºC to 200 ºC. In the present paper, the recent activity on printed electronics in Japan will be briefly summarized and the state of the low temperature curable inks is briefly reviewed.
