Claim 11:
12. An assembly, comprising: a monolithic source array, wherein the monolithic source array comprises: a dielectric plate, wherein the dielectric plate comprises a first surface and a second surface opposite from the first surface; a plurality of protrusions extending out from the first surface of the dielectric plate; and a plurality of gas distribution holes from the first surface to the second surface of the dielectric plate; and a housing attached to the monolithic source array, wherein the housing comprises: a conductive body, wherein the conductive body comprises a third surface and a fourth surface opposite from the third surface, wherein the conductive body is electrically conductive; a plurality of openings through the conductive body, wherein each of the openings surround a different one of the plurality of protrusions, wherein the plurality of openings have vertical sidewalls with a width that is uniform through a thickness of the conductive body; a plurality of channels into the fourth surface of the conductive body; wherein the channels consist of a plurality of circular portions and linear portions, the linear portions intersect at the circular portions, a cover over the channel, wherein the cover comprises a plurality of first holes, wherein each of the first holes is fluidically coupled to a gas distribution hole; and a second hole through the conductive body, wherein the second hole intersects with the channel, and wherein the second hole is fluidically coupled with the channel.
