Abstract:
A method for depositing a material onto a substrate, comprising the steps of:(a) generating at least one reactive species in an arcless, atmospheric-pressure, RF plasma discharge in a gas flowing through an annular region between an electrically conducting chamber having a closed end and an open end and a metal electrode located within the chamber and disposed such that the annular region is defined therebetween, whereby said at least one reactive species [flow] flows toward the open end of the chamber;(b) introducing a gaseous precursor species of said material into said at least one reactive species within the chamber in the region of the open end thereof and outside of the plasma discharge, said gaseous precursor species being chosen such that said precursor species reacts with at least one of said at least one reactive species, whereby a gaseous jet capable of forming said material exits through the open end of the chamber; and(c) placing said substrate in the path of the gaseous jet, whereby said material is deposited on said substrate.
