Claim 0:
1. A semiconductor processing system, comprising:
a remote plasma source (RPS);
a faceplate;
an output manifold positioned between the RPS and the faceplate, wherein the output manifold is characterized by a plurality of purge outlets that are fluidly coupled with a purge gas source;
a delivery tube extending between and fluidly coupling the RPS and the faceplate, wherein:
an upstream end of the delivery tube is characterized by a first diameter that tapers to a smaller second diameter that defines a cylindrical sidewall that defines an upper plurality of apertures that are arranged in a radial pattern, the cylindrical sidewall extending to a downstream end of the delivery tube;
each of the upper plurality of apertures is fluidly coupled with at least one of the plurality of purge outlets; and
the cylindrical sidewall defines a lower plurality of apertures that are arranged in a radial pattern and below the upper plurality of apertures.
