Original Abstract Submitted

A substrate support and a plasma processing apparatus for placing an edge ring on an electrostatic chuck with high positional accuracy. A substrate support includes: a base, a first electrostatic chuck region disposed at an upper portion of the base and having a substrate support surface, and the first electrostatic chuck holding a substrate on the substrate support surface; and a second electrostatic chuck region disposed at the upper portion of the base to surround the first electrostatic chuck region and having a ring support surface, and the second electrostatic chuck holding an edge ring on the ring support surface. The second electrostatic chuck region is provided with a positioning pin of the edge ring, the positioning pin being formed of a material having a linear expansion coefficient substantially equal to a linear expansion coefficient of a material forming the second electrostatic chuck region.
