Abstract:
Embodiments described herein relate to a faceplate for improving film uniformity. A semiconductor processing apparatus includes a pedestal, an edge ring and a faceplate having distinct regions with differing hole densities. The faceplate has an inner region and an outer region which surrounds the inner region. The inner region has a greater density of holes formed therethrough when compared to the outer region. The inner region is sized to correspond with a substrate being processed while the outer region is sized to correspond with the edge ring.
