13. Traceable Temperature Calibrations of Radiation Thermometers for Rapid Thermal Processing
Published: 11/1/2005
Author: Benjamin K Tsai
Abstract: Lightpipe radiation thermometers (LPRTs) have been successfully calibrated at NIST for rapid thermal processing (RTP) applications using a sodium heat-pipe blackbody (Na-HPBB) between 700 C and 900 C with an uncertainty of about 0.3 C (k = 1) trac ...

14. Calibration of a Low Temperature Cable-Less Lightpipe Pyrometer on the NIST Post-Exposure Bake Test Bed
Published: 10/5/2005
Authors: Benjamin K Tsai, Kenneth Gruber Kreider, William Andrew Kimes
Abstract: The advent of the cable-less lightpipe radiation thermometer (CLRT) has resulted in a significant improvement in the accuracy of lightpipe radiation thermometer calibrations and measurements. CLRT systems show great promise in noncontact measurement ...

18. In Situ Calibration of Lightpipe Radiometers in Rapid Thermal Processing Between 300 C to 700 C
Published: 9/15/2004
Authors: William Andrew Kimes, Kenneth Gruber Kreider, Dean C Ripple, Benjamin K Tsai
Abstract: Many Rapid Thermal Processing (RTP) tools are currently monitored and controlled with lightpipe radiometers (LPRTs), which have been limited to measuring temperatures above 500 C because of the low signal level below 500 C. New commercial LPRTs co ...
