Publication number: US20220112599A1
Application number: 17/644,827

Abstract:
A ceramic heater includes a disk-shaped ceramic plate having a wafer placement surface on a front surface thereof, the ceramic plate having a plasma electrode and a heater electrode embedded therein in this order, from closest to the wafer placement surface to farthest, in such a manner that the plasma electrode and the heater electrode are spaced apart from each other; a cylindrical shaft that supports the ceramic plate from a back surface of the ceramic plate; a plasma electrode connecting member arranged in the cylindrical shaft and connected to the plasma electrode; a heater electrode connecting member arranged in the cylindrical shaft and connected to the heater electrode; and a planar shield portion arranged on the back surface of the ceramic plate or embedded in the ceramic plate so as to be closer to the back surface than the heater electrode, the planar shield portion being connected to ground.
