Beschreibung
Zusammenfassung:	A plasma processing apparatus includes a metallic basic material arranged in a sample stage, a dielectric film of dielectric material disposed on an upper surface of the basic material, the dielectric film being formed through a plasma spray process; a film-shaped heater disposed in the dielectric film, the heater being formed through a plasma spray process; an adhesive layer arranged on the dielectric film; a sintered ceramic plate having a thickness ranging from about 0.2 mm to about 0.4 mm, the sintered ceramic plate being adhered onto the dielectric film by the adhesive layer; a sensor disposed in the basic material for sensing a temperature; and a controller for receiving an output from the sensor and adjusting quantity of heat generated by the heater.
