Abstract
A method for measuring a temperature of a process area is provided. A simulation computation is performed to obtain a simulation temperature. A ratio-pyrometer with two one-color modes is used to measure the temperature of the process area, and a first emissivity value and a second emissivity value are acquired. An emissivity ratio is set to a ratio of the second emissivity value to the first emissivity value, and the ratio-pyrometer in the two-color mode is used to measure the temperature of the process area.
