Manufacturing method of electro line for liquid crystal display device
摘要:
A manufacturing method of an electro line for a liquid crystal display device includes depositing a barrier layer made of a conducting material on a substrate, depositing a copper layer (Cu) on the barrier layer, wet-etching the Cu layer using a first etchant, and dry-etching the barrier layer using a second etchant using the wet-etched Cu layer as an etch mask.
