Abstract:
A semiconductor processing chamber may include a remote plasma region, and a processing region fluidly coupled with the remote plasma region. The processing region may be configured to house a substrate on a support pedestal. The support pedestal may include a first material at an interior region of the pedestal. The support pedestal may also include an annular member coupled with a distal portion of the pedestal or at an exterior region of the pedestal. The annular member may include a second material different from the first material.
