GASBOX FOR SEMICONDUCTOR PROCESSING CHAMBER

Abstract:

Exemplary semiconductor processing chambers may include a gasbox including a first plate having a first surface and a second surface opposite to the first surface. The first plate of the gasbox may define a central aperture that extends from the first surface to the second surface. The first plate may define an annular recess in the second surface. The first plate may define a plurality of apertures extending from the first surface to the annular recess in the second surface. The gasbox may include a second plate characterized by an annular shape. The second plate may be coupled with the first plate at the annular recess to define a first plenum within the first plate.
