Showerhead for fast delivery of incompatable precursors

Abstract

Disclosed herein are a showerhead and a deposition chamber containing the showerhead. The showerhead includes a first delivery network for a first precursor that comprises a first manifold connected with a first distribution system comprising a plurality of first distribution channels concentrically disposed around an axis, and a second delivery network for a second precursor that comprises a second manifold connected with a second distributions system comprising a plurality of second distribution channels concentrically disposed around the axis. The first delivery network and the second delivery network are isolated from each other within the showerhead.
