Claim 0:
1. A substrate processing system comprising:
a chamber body defining a transfer region;
a first lid plate seated on the chamber body along a first surface of the first lid plate, wherein the first lid plate defines a plurality of apertures through the first lid plate;
a plurality of lid stacks, wherein a number of the plurality of lid stacks is equal to a number of apertures of the plurality of apertures defined through the first lid plate, wherein the plurality of lid stacks at least partially define a plurality of processing regions disposed above the transfer region;
a plurality of isolators, wherein an isolator of the plurality of isolators is positioned between each lid stack of the plurality of lid stacks and a corresponding aperture of the plurality of apertures;
a plurality of annular spacers, wherein an annular spacer of the plurality of annular spacers is positioned between each isolator of the plurality of isolators and a corresponding lid stack of the plurality of lids stacks; and
a plurality of manifolds, wherein a manifold of the plurality of manifolds is seated within an interior of each annular spacer of the plurality of annular spacers, wherein:
each annular spacer comprises a base portion and an upper portion that extends upward from the base portion;
the upper portion comprises an inner section and an outer section; and
the inner section comprises a downward-extending protrusion that contacts an upper surface of one of the plurality of manifolds.
