Abstract
Magnetron plasma etchers with axial magnetic fields and hexagonal and oval cross sections were constructed. Electron magnetic confinement sustains stable low pressure collisionless plasmas and generates high flux, low energy (50 - 300 eV) ion bombardment for high rate (approximately 0. 5 mu /min for SiO2) and low radiation damage etching. Etch uniformity and normal ion bombardment can be easily controlled by plasma optics. The magnetic field adds another degree of freedom for controlling plasma parameters and in turn the etching process. The basic principle of the magnetron etching is introduced.
