摘要： An electrostatic chuck with a heater includes: a base formed of a sintered body containing alumina; an ESC electrode provided in an upper portion side in the base; and a resistance heating body embedded in a lower portion side in the base. The base is composed of a dielectric layer from the ESC electrode to an upper surface of the base, and of a support member from the ESC electrode to a lower surface of the base. In the support member, a carbon content differs between an ESC electrode neighborhood in contact with the dielectric layer and a lower region below the ESC electrode neighborhood, a carbon content in the dielectric layer is 100 wt ppm or less, the carbon content in the ESC electrode neighborhood is 0.13 wt % or less, the carbon content in the lower region is 0.03 wt % or more and 0.5 wt % or less, and the carbon content in the ESC electrode neighborhood is smaller than the carbon content in the lower region. The resistance heating body contains niobium or platinum.

摘要： An electrostatic chuck includes a base, and includes an electrode embedded in the base in parallel to a substrate mounting surface of the base. A terminal loaded into a terminal hole drilled into a back surface of the base toward the electrode is bonded to the electrode having a protruded portion with a substantially conical trapezoidal shape, which is formed on a flat surface on the terminal side of the electrode toward the terminal hole. In the protruded portion, an angle made by the flat surface on the terminal side of the electrode and an inclined surface of the protruded portion is 40° or less, and a distance from the flat surface of the electrode to a terminal-bonding surface of the protruded portion is 0.01 to 0.8 mm.
