Abstract
Methods and apparatus for forming thin films are described. A semiconductor processing chamber includes a substrate support, an electrode opposite the substrate support, the electrode having a gas inlet in a peripheral region thereof, and an edge ring disposed around a peripheral region of the substrate support, the edge ring having a first barrier and a second barrier, wherein each of the first barrier and the second barrier mates with a recess in the electrode. The edge ring provides a gas flow path through a processing zone between the substrate support and the electrode that is substantially parallel to the upper surface of the substrate support. The electrode may be powered to enhance formation of a film on a substrate.
