Abstract:
1. A method of fabricating an array substrate, the array substrate having a switching element with a gate electrode, a first insulation layer on the gate electrode, source and drain electrodes over the first insulation layer, and a transparent conductive metallic layer, the method comprising: treating a surface of the transparent conductive metallic layer with a plasma gas to remove impurities and change a lattice structure of the transparent conductive metallic layer, wherein each of the source and drain electrodes includes a metallic material, and wherein the transparent conductive metallic layer is formed on the first insulation layer and spaced apart from the source electrode; and forming a second insulation layer in physical contact with a top surface of the transparent conductive metallic layer having the surface treated with the plasma gas and over the switching element, wherein treating the surface of the transparent conductive metallic layer with plasma gas and forming the second insulation layer are performed in a same chamber.
