Exemplary semiconductor processing systems may include an output manifold that defines at least one plasma outlet. The systems may include a gasbox disposed beneath the output manifold. The gasbox may include an inlet side facing the output manifold and an outlet side opposite the inlet side. The gasbox may include an inner wall that defines a central fluid lumen. The inner wall may taper outward from the inlet side to the outlet side. The systems may include an annular spacer disposed below the gasbox. An inner diameter of the annular spacer may be greater than a largest inner diameter of the central fluid lumen. The systems may include a faceplate disposed beneath the annular spacer. The faceplate may define a plurality of apertures extending through a thickness of the faceplate.

Uniform in situ cleaning and deposition

The present disclosure relates to a cleaning assemblies, components thereof, and methods associated therewith for substrate processing chambers. In one example, a cleaning assembly for a substrate processing chamber includes a distribution ring. The distribution ring comprises a body with an inlet and an outlet. The outlet is fluidly coupled to an internal volume of the substrate processing chamber via a sidewall of the substrate processing chamber. The cleaning assembly includes a cleaning conduit configured to fluidly couple a gas manifold to the distribution ring for diverting a first portion of cleaning fluid from the gas manifold to the distribution ring.
