Abstract:
A reactor configured to subject a substrate to alternately repeated surface reactions of vapor-phase reactants, comprising:a reaction chamber that defines a reaction space; a substrate that is positioned within the reaction chamber; an plasma generating apparatus having an upper surface and a lower surface, the plasma generating apparatus being positioned in the reaction chamber such that a plasma is generated between the upper surface of the plasma generating apparatus and an upper wall of reaction chamber with no plasma being generated between the lower surface of the plasma generating apparatus and the substrate; a first precursor source that is in communication with the reaction space through an inlet; and a flow guide that is configured to direct the first precursor over the upper surface of the plasma generating apparatus, along a side of the plasma generating apparatus and to a space between the lower surface of the plasma generating apparatus and the substrate, the first precursor flowing substantially in a first direction, which is substantially parallel to the substrate.
