IPC: G01B11/06
Filed: 1985-10-18
Abstract: PURPOSE:To enable on-line measurement with high accuracy by removing the effect of light absorption or reflectivity, by using laser beam of which the wavelength is variable and calculating a film thickness on the basis of the ratio of luminous intensity and the secondary differentiated value thereof. CONSTITUTION:In an apparatus wherein a film 6 to be measured is irradiated with light and the intensity of the reflected light from said film is detected to measure the thickness of the film, a laser beam source 1 capable of varying wavelength is used as a light source and a drive current is swept by a laser current control apparatus 4 so as to successively vary a wavelength. Luminous intensity measuring devices 11, 7 are respectively provided to an incident light side and a reflected light side and the outputs of both measuring devices are secondarily differentiated on the basis of a wavelength by secondary differentiating lock-in amplifiers 13, 8. Then, the ratios of luminous intensity/secondary differentiated values in respective sides are calculated by a calculator 9 to determine the difference between the ratios of both of them and the thickness of the film 6 is calculated on the basis of the value of said difference.
