A new in situ measurement system of film thickness for thermal CVD based on thin film interference is presented. Comparing the radiation spectrum during deposition with that before deposition, we controlled the thickness of' the films with accuracy of 3nm on the thermal process where the temperature changes significantly. Using the interfi.rence of the substrate, we measured thickness of the film thinner than 2Onm.
