20140308616 | COMPOSITION OF AN AQUEOUS ETCHANT CONTAINING A PRECURSOR OF OXIDANT AND PATTERNING METHOD FOR CONDUCTIVE CIRCUIT - The present invention is primarily related to the composition of an aqueous etchant containing a precursor of oxidant and patterning methods for conductive circuits, in which the chemical structure of the precursor contains chlorine and can produce oxidants through various reactions. And, the patterned conductive circuits can be used for electronic devices, including printed electronics, sensors, displays, organic light emitting diodes (OLED), touch panels, electronic circuit boards, electrodes, electroluminescent (EL) films, antennas, and solar cells. | 10-16-2014 |
