Method and apparatus for manufacturing semiconductor device

摘要

In a method of manufacturing a semiconductor device including a capacitor, a refractory metal layer is dry-etched using a resist pattern as a mask, whereby a first electrode pattern formed of refractory metal is provided. Sidewall of the first electrode pattern is cleaned using aqueous solution of a surface active agent. Through this procedure, etching residue formed on the sidewall of the electrode pattern is removed when the electrode pattern of refractory metal is produced through dry etching method.
