    Abstract: A method for etching a metal layer formed on a substrate to form a metal line, using an amorphous carbon layer as a pattern mask. One embodiment of the method of the invention etches a metal layer formed on a substrate, for forming a metal line, by depositing an amorphous carbon layer on the metal layer, patterning the amorphous carbon layer to provide a pattern mask on the metal layer, thus exposing portions of said metal layer; and etching the exposed portions of the metal layer, to form a metal line. In an embodiment, the metal layer comprises a copper layer.
