    • In a method of fabricating a thin film transistor array substrate, an aluminum-based conductive layer is deposited onto an insulating substrate, and patterned to form a gate line assembly. The gate line assembly includes gate lines, gate electrodes, and gate pads. A gate insulating layer is formed on the substrate with the gate line assembly. A semiconductor layer, and an ohmic contact layer are sequentially formed on the gate insulating layer. A double-layered conductive film with a chrome-based under-layer and an aluminum-based over-layer is deposited onto the substrate, and patterned to form a data line assembly. The data line assembly includes data lines crossing over the gate lines, source electrodes, drain electrodes, and data pads. The chrome-based under-layer of the conductive film is patterned through dry etching while using Cl2 or HCl as the dry etching gas. A protective layer is deposited onto the substrate, and patterned to thereby form contact holes exposing the drain electrodes, the gate pads, and the data pads. Indium zinc oxide is deposited onto the substrate, and patterned to thereby form pixel electrodes connected to the drain electrodes through the corresponding contact holes, and subsidiary gate and data pads connected to the gate and data pads through the corresponding contact holes.

    • First, a conductive material made of aluminum-based material is deposited and patterned to form a gate wire including a gate line, a gate pad, and a gate electrode. A gate insulating layer is formed, and a semiconductor layer and an ohmic contact layer are sequentially formed. Next, a conductor layer including a lower layer of Cr and an upper layer of aluminum-based material is deposited and patterned to form a data wire include a data line intersecting the gate line, a source electrode, a drain electrode and a data pad. Then, a passivation layer is deposited and patterned to form contact holes exposing the drain electrode, the gate pad and the data pad, respectively. Next, an amorphous silicon layer is deposited, an annealing process is executed to form inter-layer reaction layers on the drain electrode, the gate pad and the data pad, which are exposed through the contact holes. Then, the amorphous silicon layer is removed. Next, IZO is deposited and patterned to form a pixel electrode, a redundant gate pad and a redundant data pad respectively and electrically connected to the drain electrode, the gate pad and the data pad via the inter-layer reaction layers.
