Silicon nitride films deposited on a cylindrical probe surface are removed by ion bombardment in pure N2 plasma in the chamber of the double-tubed coaxial-line-type microwave plasma chemical vapor deposition system, and removal rates of the films are measured. The experiments are carried out with variation of the probe position in the chamber and the bombardment voltage applied to the probe. It has been clarified that the removal rate is proportional to the ion flux density. From this result, general removal conditions of silicon nitride films by ion bombardment have been clarified.
