ABSTRACT:
A dry-etching method comprising the steps of forming carbon film on a substrate to be etched, forming a resist pattern on said carbon thin film, selectively etching said carbon film using said resist pattern as a mask by a plasma of a gas mixture of a gas containing fluorine atoms and a gas containing oxygen atoms which are mixed at an atomic ratio of fluorine to oxygen of 198:1 to 1:2 so as to form a carbon film pattern, and selectively etching said substrate to be etched using said carbon film pattern as a mask or said resist pattern and said carbon film pattern as masks.
