In this work we have examined the experimental low-temperature limits of 1.1μm pyrometry for the measurement of the temperature of silicon wafers and aluminum-coated silicon wafers at temperatures under 700 °C in RTP chambers. In-situ emissivity correction in the same range has also been demonstrated with a single detector for radiation and reflection measurements. Temperatures as low as 450 °C have been measured on metallized surfaces with an accuracy of better than 10 °C without any a priori knowledge of the wafer emissivity.
