    摘要: Exemplary semiconductor processing chambers may include an inlet manifold defining a central aperture. The inlet manifold may also define a first channel and a second channel, and each of the channels may extend through the inlet manifold radially outward of the central aperture. The chambers may also include a gasbox characterized by a first surface facing the inlet manifold and a second surface opposite the first. The gasbox may define a central aperture aligned with the central aperture of the inlet manifold. The gasbox may define a first annular channel in the first surface extending about the central aperture of the gasbox and fluidly coupled with the first channel of the inlet manifold. The gasbox may define a second annular channel extending radially outward of the first and fluidly coupled with the second channel of the inlet manifold. The second annular channel may be fluidly isolated from the first.

    摘要: Exemplary semiconductor processing systems may include an inductively coupled plasma source. The systems may include an RF power source that is electrically coupled with the inductively coupled plasma source. The systems may include a first gas source fluidly coupled with the inductively coupled plasma source. The systems may include a second gas source. The systems may include a dual-channel showerhead assembly defining a first plurality of apertures and a second plurality of apertures. The first plurality of apertures may be fluidly coupled with the inductively coupled plasma source. The second plurality of apertures are fluidly coupled with the second gas source.

    摘要: Exemplary semiconductor processing systems may include a chamber body comprising sidewalls and a base. The systems may include a substrate support extending through the base of the chamber body. The substrate support may include a support plate defining a plurality of channels through an interior of the support plate. Each channel of the plurality of channels may include a radial portion extending outward from a central channel through the support plate. Each channel may also include a vertical portion formed at an exterior region of the support plate fluidly coupling the radial portion with a support surface of the support plate. The substrate support may include a shaft coupled with the support plate. The central channel may extend through the shaft. The systems may include a fluid source coupled with the central channel of the substrate support.
