Abstract
A method of manufacturing electronic components using intaglio transfer printing for improving printing yield. Intaglio having a dual releasing layer structure is used. In this structure, first releasing layer is formed on the surface of intaglio by chemical absorption, and second releasing layer is formed on the first releasing layer by physical adsorption. This structure allows intaglio to have stable releasing ability, thereby improving the printing yield. In addition, because second releasing layer can be added as required, the printing yield is not decreased even when the intaglio is repeatedly used for printing. Furthermore, the dual releasing layer structure can improve durability of the releasing ability of intaglio . As a result, patterns for electronic components can be formed on substrates at an excellent yield.
