Abstract:
1. A method of depositing a layer of material on a substrate, comprising: generating radicals as precursor molecules by applying voltage across electrodes in a reactor that is at least partially enclosed within a process chamber; injecting the precursor molecules into a reactor chamber formed in the reactor; injecting the precursor molecules towards substrate by a reactor; applying a magnetic field by magnets placed within the process chamber and attached to the reactor, the magnet field traversing paths of the precursor molecules traveling within the reactor chamber to the substrate to cause spiral movements of the precursor molecules relative to a surface of the substrate; exposing the surface of the substrate to the precursor molecules making the spiral movements to cause the surface of the substrate to absorb or react with the precursor molecules; and causing the substrate to move in parallel to the surface of the substrate to expose different parts of the substrate to the precursor molecules.
