Abstract
Apparatus and method for non-contact temperature measurement of a film growing on a substrate which accounts for the change in emissivity due to the change in film thickness. The system employs an adaptively calibrated pyrometer wherein the substrate emittance is continuously computed so that the temperature measurement is accurate regardless of the emittance variation. The new system is easily constructed by adding data processing system software and hardware to conventional pyrometers.
