First Claim
Patent Images
1. A plasma surface treating apparatus comprising:
- a rotary electrode capable of supporting a sample to be treated for rotation together therewith;
a counterelectrode confronting said rotary electrode and having an opening defined therein;
a direct current source disposed between said rotary electrode and said counterelectrode for applying a voltage; and
an ion source disposed in face-to-face relationship with said opening in said counterelectrode for forming a pattern on said sample.

Abstract
In a plasma surface treating method, a sample to be treated is supported on a first electrode within a vacuum vessel and a second electrode is caused to confront the first electrode. Active species of negative ions are then generated by means of a direct current glow discharge produced in an abnormal glow discharge region and are subsequently impinged upon a surface of the sample to induce a chemical reaction with the sample.
