    摘要: PURPOSE: An etchant composition is provided to avoid the residue generation after an etching process while not damaging a photoresist in an etching process and to improve productivity in the manufacture of an electronic component substrate such as a flat panel display. CONSTITUTION: An etchant composition for a transparent electrode layer comprises inorganic acids, compound including ammonium(NH4+), cyclic amine compound, and remaining amount of water. The etchant composition further includes at least one selected from surfactants, metal ion scavenger and corrosion inhibitor. A method for etching the transparent electrode layer comprises the steps of: forming a transparent electrode layer on a substrate; forming a photoresist pattern on the transparent electrode layer; and etching the transparent electrode layer using the etchant.
