摘要： A temperature measurement apparatus includes a light source; a first splitter that splits a light beam into a measurement beam and a reference beam; a reference beam reflector that reflects the reference beam; an optical path length adjustor; a second splitter that splits the reflected reference beam into a first reflected reference beam and a second reflected reference beam; a first photodetector that measures an interference between the first reflected reference beam and a reflected measurement beam obtained by the measurement beam reflected from a target object; a second photodetector that measures an intensity of the second reflected reference beam; and a temperature calculation unit. The temperature calculation unit calculates a location of the interference by subtracting an output signal of the second photodetector from an output signal of the first photodetector, and calculates a temperature of the target object from the calculated location of the interference.

摘要： In a method of controlling the temperature of an in-chamber member used in a plasma processing apparatus that processes a target substrate with plasma, a plurality of power-feeding portions is provided in the in-chamber member and the in-chamber member is heated by supplying electric power thereto through the power-feeding portions. A resistance value or resistivity of the in-chamber member is measured and the electric power is controlled based on the temperature of the in-chamber member estimated from the resistance value or resistivity. The in-chamber member includes one or more annular members arranged around the target substrate. The in-chamber member is a member making contact with plasma within a chamber and existing near the target substrate.
