摘要:
The present invention relates to a method for increasing the etching capacity of a copper/molybdenum alloy film used in the manufacture of TFT-LCD. The method of the present invention can increase the etching capacity of an etchant by recovering the degradation of etching properties such as an etch rate, a taper profile, and etch linearity which are generated when etching is repeated using the etchant with the copper/molybdenum alloy film, thereby substantially reducing production costs for TFT-LCD, and the like.
摘要:
The present invention provides an etchant composition for a metal film comprising at least one film selected from an indium-based transparent conductive film, an aluminum-based metal film and a titanium-based metal film, used for the interconnect of a pixel electrode, a gate electrode, a source electrode and a drain electrode. The etchant composition is excellent in etching characteristics to an indium-based transparent conductive film, an aluminum-based metal film and a titanium-based metal film, respectively, and particularly to an Al-La-based alloy film. In addition, the etchant composition can effectively etch a tri-layered film comprising an indium-based transparent conductive film, an Al-La-based alloy film and a titanium-based metal film at a time.
摘要:
The present invention relates to an etchant composition for the formation of a metal line. The etchant composition can wet-etch, in a batch, a single-layer film formed of one or more metals selected from a group consisting of titanium, titanium alloy, aluminum, and an aluminum alloy, or a multilayer film including a double-layer film, thus simplifying the etching process and improving productivity. Further, the etchant composition of the present invention has a high etching rate, prevents damage to a lower film and equipment, enables uniform etching, provides excellent etching characteristics, eliminates the need for expensive equipment, is advantageous when used for large display devices, and provides remarkable economical advantages.
