Research Abstract

A plasma can be generated locally around the electrode under the condition of atmospheric pressure because of the small mean free path of gas molecules. However, generation of small plasma for high-rate etching especially less than 1 mm is very difficult due to thermal limitations of needle-like electrodes or very thin wire electrodes. Thus, we proposed a novel electrode with a narrow slit and succeeded in generation of a narrow groove less than 0.1 mm.
