Abstract:
A method of fabricating a conductive pattern includes forming a conductive metal material layer and a conductive capping material layer on a substrate, forming a photoresist pattern as an etching mask on the conductive capping material layer, forming a first conductive capping pattern by etching the conductive capping material layer with a first etchant, forming a conductive metal layer and a second conductive capping pattern by etching the conductive metal material layer and the first conductive capping pattern with a second etchant, and forming a conductive capping layer by etching the second conductive capping pattern with a third etchant. The second conductive capping pattern includes a first region overlapping the conductive metal layer and a second region not overlapping the conductive metal layer, and the forming of the conductive capping layer includes etching the second region of the second conductive capping pattern to form the conductive capping layer.
