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.
