Role of ions in SiO2 deposition with pulsed and continuous helicon plasmas*

Abstract: Good-quality silicon dioxide films have been deposited
at low temperature (200 °C) using continuous and pulsed oxygen/silane
plasmas coupled in a high-density, low-pressure helicon reactor. Although
the total ion flux determines many of the structural properties of the
deposited oxide, we have found that silicon-containing ions contribute
to the film growth (up to 50 %) and appear to be responsible for the
measured compressive stress.
