Abstract:
1. A method of treating a surface of a substrate or depositing a layer of material on a substrate, comprising: injecting a first gas into a plasma chamber of a plasma reactor to generate radicals by plasma; injecting the generated radicals into a reaction chamber of the plasma reactor via at least one perforation between the reaction chamber and the plasma chamber; shielding the substrate from undesirable irradiation generated in the plasma chamber using an electrically conductive member placed between the at least one perforation and the substrate, the electrically conductive member configured to block straight linear paths between the plasma chamber and the substrate; injecting, via a channel formed in the electrically conductive member, a second gas into the reaction chamber; and injecting the radicals to a portion of the substrate passing the reaction chamber.
