Abstract
Exemplary semiconductor processing chambers may include a chamber body. The chambers may include a substrate support disposed within the chamber body. The substrate support may define a substrate support surface. The chambers may include a showerhead positioned supported atop the chamber body. The substrate support and a bottom surface of the showerhead may at least partially define a processing region within the semiconductor processing chamber. The showerhead may define a plurality of apertures through the showerhead. The bottom surface of the showerhead may define an annular groove or ridge that is positioned directly above at least a portion of the substrate support.
