Title 

New Copper Fine Particle Systems for Low Temperature Sintering

 

Abstract:

A conductive paste was prepared with submicrometer-sized copper fine particles of 130 nm. After drying, an oxidation-reduction two-step sintering process was proposed for these submicrometer-sized copper fine particles to obtain low-resistivity layers at a very low temperature as 200 or 150 C. The optimized conditions gave a low resistivity of 8.2 × 10^-6 Ω cm, even when the particles were covered by a common polymer. Our results suggest that the formation of the small copper oxide prominences on the surface of the copper fine particles could be reduced at low temperatures, forming connected submicrometer-sized metallic copper particles. Recently, we have further succeeded to establish a novel low cost sintering process of copper fine particles to copper conductive layer at as low as 100 °C without reductive gas flow. Sintering of a mixture of copper particles and copper-based metal-organic-decomposition (MOD) ink, gave a copper film with high packing density and low resistivity (9 × 10^-6 Ω m). This novel process may open a new strategy in the field of printed electronics.
