Abstract: PURPOSE:To make it possible to inspect easily and with enough precision such a change as a protuberance and a swell, which are generated due to a foreign substance, in a resist film by visual observation by combining a light source of polychromatic light with a specified band-pass filter. CONSTITUTION:The distribution of the reflectivity of a resist film, which is the same one as a resist applied substrate 11 which is an object of inspection and has nearly a uniform resist film thickness, to a wavelength is measured. As a result, the reflectivity is assumed, for example, to be given the minimum value in wavelengths of 520 nm and 710 nm and the maximum value in wavelengths of 470 nm and 610 nm. Then, a band-pass filter 13 is arranged before a light source 12 and selected lights 15 only for inspection are irradiated on a resist film 11b. The transmission band is assumed to be between the wavelengths 470 nm and 610 nm to correspond to the extremal values before and after the wavelength 520 nm, in which the reflectivity becomes the minimum value, and also, a wavelength band including the wavelength of 520 nm to correspond to the minimum value. This wavelength band must be within a wavelength band wherein the resist film 11b is not photosensitized. In this state, a foreign substance 16, for example, which is interposed between a substrate 11a and the resist film 11b, is detected by visual observation.
