Abstract:
In various embodiments, etchants featuring (i) mixtures of hydrochloric acid, methanesulfonic acid, and nitric acid, or (ii) mixtures of phosphoric acid, methanesulfonic acid, and nitric acid, are utilized to etch metallic bilayers while minimizing resulting etch discontinuities between the layers of the bilayer.

Claim (Index 92):
A method of forming an electrode of a thin-film transistor, the method comprising:\n providing a base layer comprising at least one of silicon or glass; depositing over the base layer a barrier layer comprising molybdenum and nickel; depositing over the barrier layer a conductor layer comprising copper; forming a mask layer over the barrier layer; patterning the mask layer to reveal a portion of the conductor layer, a remaining portion of the mask layer at least partially defining a shape of the electrode; and thereafter, applying an etchant to remove portions of the conductor layer and the barrier layer not masked by the patterned mask layer, thereby forming a sidewall of the electrode comprising (a) an exposed portion of the barrier layer, (b) an exposed portion of the conductor layer, and (c) an interface between the exposed portion of the barrier layer and the exposed portion of the conductor layer.
