    Abstract: An etchant including: persulfate; a fluorine-containing compound; a chlorine-containing compound; a cyclic amine compound; an inorganic acid; a first compound; and water, wherein the first compound is a compound containing: a sulfonic group, a sulfonic acid group, or a combination thereof; and an amine group, and an interfacial permeation inhibition index (Y) of the etchant is a value of at least about 0.10 and not more than about 0.35, the interfacial permeation inhibition index (Y) being a value calculated by Equation 1:


    Y=1.4×10−4×M(X1)+1.3×10−4×M(X2)+1.45×10−3×M(X3)+1.5×10−5×M(X1)×M(X2)+1.6×10−3M(X1)×M(X3)+6.5×10−4×M(X2)×M(X3)  Equation 1

    The description of Equation 1 is as in the specification.
