Wafer Emissivity Effects on Light Pipe Radiometry in RTP Tools
Calibration of Radiation Thermometers in Rapid Thermal Processing Tools
We investigated the effect of different silicon wafer emissivities and the effect of low emissivity films on rapid thermal processing RTP wafer temperature measurements using lightpipe radiation thermometers LPRTs These tests were performed in the NIST RTP test bed We used a NIST thinfilm thermocouple TFTC calibration wafer to calibrate the LPRTs in situ The measurement of LPRTs

Some educational resources will state that the temperature for RTP is 20 o C 29315 K and some will state its 25 o C 29815 K Please note that the volume of 1 mole at RTP would still be 24 dm 3 or 24 L and it will usually be stated in a question that you are working at RTP Calculating at RTP
Lightpipe radiation thermometers LPRTs are the sensor system of choice in RTP tools They can be calibrated against blackbodies with an uncertainty k1 less than 03 C In an RTP tool however account must be made for wafer emissivity and waferchamber interreflections or else temperature measurement uncertainties will be orders of magnitude higher
