PREPARATION METHOD OF ELECTROCONDUCTIVE COPPER PATTERNING LAYER AND COPPER PATTERNING LAYER FORMED THEREFROM

摘要

PURPOSE: A manufacturing method of an electro-conductive copper pattern layer, and a copper pattern layer formed therefrom are provided to form a copper pattern layer without preparing a space to maintain an inert gas atmosphere. CONSTITUTION: A manufacturing method of an electro-conductive copper pattern layer comprises the following steps: preparing a reducing agent containing copper dispersion solution by mixing a copper group particle and a reducing agent; forming a reducing agent containing copper group particle pattern layer by printing or filling the dispersion solution to a base material with a constant shape; and plasticizing the pattern layer among air. The copper group particle is selected form the group consisting of a copper particle, a cuprous oxide particle and their mixture.
