Abstract: An etchant includes about 0.1 percent by weight to about 30 percent by weight of ammonium persulfate (NH4)2S2O8, about 0.1 percent by weight to about 10 percent by weight of an inorganic acid, about 0.1 percent by weight to about 10 percent by weight of an acetate salt, about 0.01 percent by weight to about 5 percent by weight of a fluorine-containing compound, about 0.01 percent by weight to about 5 percent by weight of a sulfonic acid compound, about 0.01 percent by weight to about 2 percent by weight of an azole compound, and a remainder of water. Accordingly, the etchant may have high stability to maintain etching ability. Thus, manufacturing margins may be improved so that manufacturing costs may be reduced.

Abstract translation: 蚀刻剂包括约0.1重量％至约30重量％的过硫酸铵（NH 4）2 S 2 O 8，约0.1重量％至约10重量％的无机酸，约0.1重量％至约10重量％的 约0.01重量％至约5重量％的含氟化合物的乙酸盐，约0.01重量％至约5重量％的磺酸化合物，约0.01重量％至约2重量％ 的唑类化合物，剩余的水。 因此，蚀刻剂可能具有高稳定性以保持蚀刻能力。 因此，可以提高制造裕度，从而可以降低制造成本。
