摘要：A method of forming an array substrate for u in a thin film transistor liquid crystal display (TFT-LCD) device includes forming a first metal layer on a substrate,
patterning the first metal layer to form a gate line and a gate electrode extended from
the gale line, forming a gate insulation layer on the substrate to cover the patterned first metal layer, forming an active layer on the gate insulation layer and over the gate electrode, forming an ohmic contact layer on the active layer, forming a cond metal layer on the gate insulation layer to rover the ohmic contact layer and the active layer, forming a third copper metal layer on the cond metal layer, simultaneously patterning the cond metal layer and the third copper metal layer to form a double-layered data line, a double-layered source electrode and a double-layered drain electrode using an etchant that includes hydrogen peroxide (HO), a HOstabilizer, and a neutral salt, and forming a pixel electrode contacting the double-layered drain electrode.
