| description | Embodiments of the present invention generally provide a method and apparatus that may be utilized for deposition of Group III-nitride films using MOCVD and/or HVPE hardware. In one embodiment, the apparatus is a showerhead assembly made of multiple sections that are isolated from one another and attached to a top plate. Each showerhead section has separate inlets and passages for delivering separate processing gases into a processing volume of a processing chamber without mixing the gases prior to entering the processing volume. In one embodiment, each showerhead section includes a temperature control manifold for flowing a cooling fluid through the respective showerhead section. By providing multiple, isolated showerhead sections, manufacturing complexity and costs are significantly reduced as compared to conventionally manufacturing the entire showerhead from a single block or stack of plates. |
