Original Abstract Submitted

An edge ring includes a ring body having an axis parallel to a first direction; and a plurality of protrusions provided at an inner side surface of the ring body and protruding toward the axis, the plurality of protrusions being spaced apart from each other in a circumference direction of the edge ring, wherein a first distance between the axis and a first point on the inner side surface of the ring body between two adjacent protrusions of the plurality of protrusions is larger than a second distance between the axis and a second point on the inner side surface of the ring body at which a protrusion of the plurality of protrusions is provided.
