Exemplary embodiments of the present invention provide a metal wiring etchant. A metal wiring etchant according to an exemplary embodiment of the present invention includes ammonium persulfate, an organic acid, an ammonium salt, a fluorine-containing compound, a glycol-based compound, and an azole-based compound.
摘要:
An etchant for a metal is described. In one example, the etchant includes ammonium persulfate ((NH4)2S2O8), an azole compound and water. The etchant does not include hydrogen peroxide. Thus, the etchant may etch a metal layer including copper so that an etched copper layer has a tapered profile. Furthermore, the etchant may have a high stability to maintain etching ability for a longer time. Thus, manufacturing margins may be improved so that manufacturing costs may be reduced.

摘要:
An etching composition, a method of forming a metal pattern using the etching composition, and a method of manufacturing a display substrate are disclosed. The etching composition includes about 0.1% by weight to about 25% by weight of ammonium persulfate, about 0.1% by weight to about 25% by weight of an organic acid, about 0.01% by weight to about 5% by weight of a chelating agent, about 0.01% by weight to about 5% by weight of a fluoride compound, about 0.01% by weight to about 5% by weight of a chloride compound, about 0.01% by weight to about 2% by weight of an azole-based compound and a remainder of water. Thus, a copper layer may be stably etched to improve a reliability of manufacturing the metal pattern and the display substrate.
摘要:
A vacuum roll-to-roll device includes: a first chamber; a second chamber neighboring the first chamber; a shutter disposed between the first chamber and the second chamber; a sealing member attached to the shutter; and a roll-type substrate which moves from the first chamber to the second chamber through the sealing member. A thickness of a lateral side of the roll-type substrate decreases in a direction toward an edge thereof.
