Abstract:
An etchant composition includes about 0.5 weight % to about 20 weight % of persulfate, about 0.01 weight % to about 2 weight % of a fluoride compound, about 1 weight % to about 10 weight % of an inorganic acid, about 0.5 weight % to about 5 weight % of a cyclic amine compound, about 0.1 weight % to about 10.0 weight % of a compound having an amino group and a sulfonic acid, about 0.1 weight % to about 15.0 weight % of an organic acid or a salt thereof, and water to 100 weight % of the etchant composition.
