Filed: 1991-11-20
Abstract: PURPOSE:To detect very small foreign particles in a fine pattern by making linearly polarized light rays from a light source group having a plurality of wavelengths to incident to a very small area on a sample and separating the scattered light rays of the linearly polarized light rays into different wavelength components, and then, measuring the intensities of the separated wavelength components. CONSTITUTION:Scattered light rays from one point on a wafer 18 irradiated with S-polarized laser beams 14 and 17 respectively having wavelengths lambda1 and lambda2 are separated into scattered light rays having the wavelengths lambda1 and lambda2 by means of a dichroic mirror 20 after they are condensed through an objective 19. The scatter light rays separated by wavelengths are respectively separated into P-polarized components and S-polarized components through polarization beam splitters 21 and 22 and converted into electric signals by means of photoelectric conversion elements 23-26. Then foreign matters are detected by finding the degrees of polarization of both wavelengths from the signal intensities of the elements 23 and 24 and the elements 25 and 26 by means of an electric circuit and detecting the wavelength dispersion characteristic of the degrees of polarization.
