Abstract The inventive concepts provide a method of completely removing a damage region of a surface of an etch target layer after plasma-etching the etch target layer. The method includes performing a first post-etch plasma treatment process using a first post-treatment gas on the plasma-etched etch target layer. A polarity of ions of the first post-treatment gas may be the same as a polarity of bias power applied to a stage in a plasma apparatus.
