Claim 5:
6. A substrate processing chamber, comprising:
an isolator;
an annular spacer positioned atop the isolator;
a manifold seated atop the isolator and positioned within an interior of the annular spacer, wherein:
a top surface of the manifold is at a lower height than a top portion of the annular spacer; and
the manifold defines a plurality of apertures therethrough; and
the top surface of the manifold and a bottom surface of the manifold comprise a conductive material; and

a plurality of pins positioned between the isolator and the manifold, wherein the plurality of pins elevate the bottom surface of the manifold above a top surface of the isolator such that a gap is formed between the bottom surface of the manifold and the top surface of the isolator.
