    Abstract: Disclosed is a plasma processing apparatus comprising a plasma electrode, an electrostatic chuck, and a diode board. The electrostatic chuck includes a microheater layer and a chuck electrode. The microheater layer includes an inner heater part and an outer heater part. The inner heater part includes a first inner heater in a first inner region that circumferentially surrounds a center of the microheater layer, and a second inner heater in a second inner region that circumferentially surrounds the first inner region. The outer heater part includes a first outer heater in a first outer region that circumferentially surrounds the second inner region, and a second outer heater in a second outer region that circumferentially surrounds the first outer region. A distance between centers of the first and second outer heaters is less than that between centers of the first and second inner heaters.
