    摘要: In an etchant for etching a capping layer having etching selectivity with respect to a dielectric layer, the capping layer changes compositions of the dielectric layer, to thereby control a threshold voltage of a gate electrode including the dielectric layer. The etchant includes about 0.01 to 3 percent by weight of an acid, about 10 to 40 percent by weight of a fluoride salt and a solvent. Accordingly, the dielectric layer is prevented from being damaged by the etching process for removing the capping layer and the electric characteristics of the gate electrode are improved.
