Claim 7:
8. A semiconductor processing system, comprising:
a remote plasma source (RPS);
a faceplate;
a purge gas plenum;
a delivery tube coupled with the RPS and extending between and fluidly coupling the RPS and the faceplate, wherein:
the delivery tube is characterized by a central axis and a cylindrical sidewall that extends from an upstream end of the delivery tube to a downstream end of the delivery tube;
the cylindrical sidewall defines a plurality of apertures that are arranged in a radial pattern about the central axis;
each of the plurality of apertures is fluidly coupled with the purge gas plenum; and
each of the plurality of apertures is angled away from the central axis.
