  • Patent number: 8541093
    Abstract: A method for high resolution ink-jet print using a pre-patterned substrate employs an ink-jet printing device including an ink-jet head for discharging conductive ink droplets and a driving stage for supporting a substrate to which the conductive ink droplets are hit, to draw a fine line width pattern on the substrate. The method includes (A) forming a stripe pattern with repeated stripes on a substrate surface on which a fine line width pattern will be formed, thereby preparing a pre-patterned substrate; (B) loading the substrate to the ink-jet printing device; and (C) injecting conductive ink droplets to a substrate region where the stripe pattern is formed. An equivalent interval (d) of the stripe pattern and a fine line width (D) of the drawn fine line width pattern satisfy a relation of d<<D, and the hit ink droplets are flowed in an anisotropic form within the region.

  • Patent number: 8394465
    Abstract: A preparation method of an electroconductive copper patterning layer includes (Step 1) preparing a dispersion solution of copper-based particles selected from the group consisting of copper particles, copper oxide particles, and their mixtures; (Step 2) forming a copper-based particle patterning layer by printing or filling the dispersion solution of copper-based particles to a substrate into a predetermined shape; and (Step 3) irradiating laser to the copper-based particle patterning layer to burn and interconnect the copper-based particles contained in the copper-based particle patterning layer. This preparation method burns a copper-based particle patterning layer with a strong energy within a short time by using laser. Thus, it is possible to obtain a copper patterning layer that is hardly oxidized even in the atmosphere, so a copper patterning layer with excellent electric conductivity is formed.
