Abstract

PURPOSE:To enable acceleration by a method wherein a reactive gas, in which chlorine molecules or carbon atoms covalence-bond, is introduced, and a metallic silicide film having the high melting point is etched on an electrode, on which a carbon plate is placed and which is energized with high frequency. CONSTITUTION:One electrode 14 between a pair of electrodes mutually arranged oppositely is grounded, unified with a vacuum vessel 15 and used as an anode, and high-frequency power is applied from 22 and 23 employing the other electrode 13 as a cathode. Consequently, a reactive gss introduced from a gas introducing port 17 such as chlorine gas or a gas in which carbon atoms and chlorine atoms covalence-bond is activated by glow discharge, plasma is formed, and a metallic silicide film 16 having the high melting point on a carbon plate 25 pasted on the electrode 13 is etched using positive ions in the plasma positively as an etchent. Thus, etching is accelerated, and under-cuts are removed.
