Cu based Conductive Materials for Printed Electronics (Printed Electronics Europe 2013)

1. Low resistivity Cu conductive layer

2. Screen printing or Ink-jet printing

3. Highly reliable conductive layer

4. Low temperature treatment for film substrate such as PET film

 

Cu based conductive materials will be introduced as a paste for screen printing or an ink for Ink-jet printing.

 

We recommend that patterned printed layer is treated at 180 ℃ under diluted reactive gas atmosphere, then the conductive layer whose conductivity is around 3 micro ohm*cm almost similar to metallic Cu can be obtained. And, if we treat them around 130 ℃ using film substrate, around 14 micro ohm*cm conductive layer can be observed. Those conductive layers show excellent reliability as same as Cu foil.

I graduated from Tokyo Institute of Technology in 1982 and received the degree of doctor of Engineering. I joined Hitachi Chemical Co., Ltd . In 1983, and engaged in the development of the materials for Printed Circuit Boards as well as die bonding materials for semiconductor devices.

 

Currently, I am a general manager of the High-performance Materials

R&D Center of Tsukuba Research Laboratory. My technical background is polymeric materials and science.

Hitachi Chemical Co., Ltd. was established in 1962, independent from Hitachi Ltd., and the headquarter is located in Tokyo. In 2010, paid-in capital was 15,454 million Japanese YEN, non-consolidated sales was 263 billion Japanese YEN, and the number of employee is 4,095. The principal lines of business are electronics related materials, advanced performance resins & materials, life-science & pharmaceuticals, carbon & ceramics, and automotive related products.
