Embodiments described herein include processes and apparatuses relate to epitaxial deposition. A method for epitaxially depositing a material is provided and includes positioning a substrate on a substrate support surface of a susceptor within a process volume of a chamber body, where the process volume contains upper and lower chamber regions. The method includes flowing a process gas containing one or more chemical precursors from an upper gas inlet on a first side of the chamber body, across the substrate, and to an upper gas outlet on a second side of the chamber body, flowing a purge gas from a lower gas inlet on the first side of the chamber body, across the lower surface of the susceptor, and to a lower gas outlet on the second side of the chamber body, and maintaining a pressure of the lower chamber region greater than a pressure of the upper chamber region.

Exemplary deposition methods may include introducing hydrogen into a processing chamber, a powder disposed within a processing region of the processing chamber. The method may include striking a first plasma in the processing region, the first plasma including energetic hydrogen species. The method may include exposing the powder to the energetic hydrogen species in the processing region. The method may include chemically reducing the powder through a reaction of the powder with the energetic hydrogen species. The method may include removing process effluents including unreacted hydrogen from the processing region. The method may also include forming a layer of material on grains of the powder within the processing region.

A showerhead assembly includes a support structure and a porous plate. The support structure includes a support feature. The porous plate has a thermal conductivity of at least about 50 W/(mK) and includes a plurality of pores having an average diameter of less than about 100 um, wherein at least a portion of a perimeter of the porous plate rests on the support feature. The showerhead may be included within a processing chamber that is utilized to process a substrate.
