    Abstract: Implementations of the present disclosure generally relate to an apparatus for reducing particle contamination on substrates in a plasma processing chamber. The apparatus for reduced particle contamination includes a chamber body, a lid coupled to the chamber body. The chamber body and the lid define a processing volume therebetween. The apparatus also includes a substrate support disposed in the processing volume and an edge ring. The edge ring includes an inner lip disposed over a substrate, a top surface connected to the inner lip, a bottom surface opposite the top surface and extending radially outward from the substrate support, and an inner step between the bottom surface and the inner lip. To avoid depositing the particles on the substrate being processed when the plasma is de-energized, the edge ring shifts the high plasma density zone away from the edge area of the substrate.
