METHOD FOR THE TEMPERATURE MEASUREMENT OF SUBSTRATES IN A VACUUM CHAMBER

摘要

The invention relates to a temperature-measuring system, comprising a temperature sensor and a reference body, wherein means for determining temperature changes of the reference body and/or for control of the temperature of the reference body are provided. When the temperature measuring-system is used in a vacuum, the reference body forms no substantial material thermal bridges to the temperature sensor and the reference body shields the temperature sensor with respect to the environment in such a way that only radiation that comes from the surfaces of the reference and from surfaces of which the temperature is to be determined reaches the surface of the temperature sensor.
