Last updated:
Abstract:
Exemplary semiconductor processing chambers may include a gasbox characterized by a first surface and a second surface opposite the first surface. The gasbox may define a central aperture. The gasbox may define an annular channel extending about the central aperture. The annular channel may be fluidly accessible from the first surface of the gasbox. The gasbox may further define a plurality of outlet apertures extending from the annular channel through the second surface of the gasbox.
