  • Publication number: 20170009348
    Abstract: A chemical deposition apparatus having conductance control, which includes a showerhead module having a faceplate and a backing plate, the showerhead module including a plurality of inlets which deliver reactor chemistries to a cavity and exhaust outlets which remove reactor chemistries, a pedestal module configured to support a substrate and which moves vertically to close the cavity between the pedestal module and an outer portion of the faceplate, and at least one conductance control assembly, which is in fluid communication with the cavity via the exhaust outlets. The at least one conductance control assembly selected from one or more of the following: a ball valve assembly, a fluidic valve, magnetically coupled rotary plates, and/or a linear based magnetic system.

  • Patent number: 7544398
    Abstract: The invention relates to methods for producing doped thin layers on substrates comprising the steps of depositing a dopant precursor on the substrate via an atomic layer deposition technique; and exposing the deposited dopant precursor to radicals. The methods can further comprise depositing a compound adjacent the dopant metal via an atomic layer deposition technique; and exposing the deposited compound to radicals, thereby providing a host. The invention relates to articles comprising approximately atomically thin layers of metals or metal oxides doped with at least one different metal or metal oxide. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
