摘要
An electron cyclotron resonance (ECR) plasma etching process using an ECR etching apparatus having a plasma generation chamber (1) and a reaction chamber (2), and gas supply entrances provided in each chamber, comprising the steps of: directing microwaves into said plasma generation chamber, applying a magnetic field to said plasma generation chamber, supplying to the plasma generating chamber (1) a first gas for generating a plasma, and supplying to the reaction chamber (2) a second gas for generating a deposit of a protective film.
