Optimally stable electron cyclotron resonance plasma generation for precise ulsi patterning

Research output: Contribution to journalConference articlepeer-review


This paper discusses microwave absorption around the electron cyclotron resonance (ECR) region in relation to the magnetic field profiles and microwave conditions, and shows how to achieve stable, uniform and efficient microwave absorption in an ECR plasma to prevent the instability. A high-performance multi-coil system and a new microwave introduction method developed for stable plasma generation are described. Experimental results show that sufficiently precise patterning suitable for practical use is achieved.
