摘要
The general principles of operation of passive and active pyrometry methods are considered. The usefulness of ratio, multiratio, approximation, and enhanced emissivity methods to unknown and changing emissivity situations is analyzed. A spectral functional for the emissivity is postulated to give the theoretical limit of accuracy of any passive method. PI novel passive - active method, with accuracy better than 1%, for semiconductor wafer measurement is described and demonstrated through on-line measurement in Rapid Thermal Chemical Vapor Deposition process.
