Abstract: PURPOSE:To measure the thickness of a thick film by utilizing the fluorescence emitted from the film by providing an optical means which introduces the fluorescence to a photodetector, a photodetector for the fluorescence and means for processing and storing the output from the photodetector. CONSTITUTION:The fluorescence is made incident on the photoelectric surface of a photomultiplier tube 12 by a lens 10 after transmission through a half mirror 5 and a filter 9 for cutting the light of 5,145Angstrom  wavelength which is excitation light. The fluorescence is generated from all the photoresists existing in the optical path of laser light 2 but the fluorescence to be made incident on the multiplier 12 is only the fluorescence generated near 15 the focal position. The quantity of the fluorescence is thereupon measured while a glass substrate 7 attached with a photoresist 8 is moved at a constant speed V toward a lens 6. If time T is known, the moving speed of the substrate 7 is V and therefore the film thickness is estimated to be V.T. The measurement of the thickness of the thick film by using the fluorescence is thus made possible by providing the means for processing and storing the output from said photodetector.
