Paper Abstract

The effective emissivity of silicon varies with both temperature and the backside roughness of a wafer. Both of these variations need to be accounted for in the calibration of infrared optical pyrometers used in rapid thermal processing. A fully integrated hardware and software approach is described which calibrates the optical pyrometer over a temperature range of 350°C to 1275°C and provides for recalibration due to wafer to wafer variations in effective emissivity based on room temperature optical characterization of wafer backsides.
