Abstract
PURPOSE:To accurately form a pattern and to improve the state of the pattern by removing an unnecessary resist residue by oxygen plasma, and then vapor etching to form the pattern. CONSTITUTION:When it is exposed with an oxygen plasma 3, a resist residue 2b on an SiN film 1c laminated together with an SiO2 film 1b on a wafer 1b formed by etching is removed, but since a resist pattern 2a is thick, it is not completely removed but remains. When it is treated by vapor etching 3 in this state, a pattern is formed accurately on the film 1c in good state.
