Abstract:
A method for coating a component for use in a semiconductor chamber for plasma etching includes providing the component and loading the component in a deposition chamber. A pressure in the deposition chamber is reduced to below atmospheric pressure. A coating is deposited on the component by spraying an aerosol comprising a suspension of a first type of metal oxide nanoparticle and a second type of metal oxide nanoparticle onto the component at approximately room temperature.
Abstract:
To generate a plasma for processing a workpiece, an electron beam is introduced into a plasma reactor chamber by radial injection using an annular electron beam source distributed around the circular periphery of the chamber to provide azimuthal uniformity. The electron beam propagation path is tilted upwardly away from the workpiece, either by tilting the electron beam source or by a magnetic field. In other embodiments, there are plural opposing electron beams from linear electron beam sources directed toward the center of the plasma reactor chamber.
