Abstract

PURPOSE:To safely operate and to freely select selective ratio as well by a method wherein gas for plasma etching is formed by mixing vapor phase hexaphloro benzene with freon gas or oxygen gas. CONSTITUTION:Hexafluorobenzene C6F6 easily permits to generate CF3<+>, CF2<++> which etch a silicon oxide film. However, in the case of single gas only, the amount of the generation of the CF3<+>, CF2<++> becomes excessive. Therefore, gas mixing the hexafluoro benzene (C6F6) with freon gas or oxygen is flowed into a chamber to control the amount of the generation. The mixing ratio of the hexafluoro benzene to freon gas or oxygen can be selected at any value in accordance with etching condition such as selective ratio. And as to etching for the silicon oxide film, the vicinity of the mixing ratio of about 1:1 is perferable and dilution is previously made by inactive gas such as argon, helium or the like.
