Abstract: A surface inspection apparatus includes an illumination means for illuminating a pattern formed through a predetermined pattern forming process containing a process of exposure of a resist layer formed on a substrate having a periodicity with a linearly polarized light, a setting means for setting a direction of the substrate such that a plane of vibration of the linear polarization and a direction of repetition of the pattern are obliquely to each other, an extraction means for extracting a polarization component having a plane of vibration perpendicular to that of the linear polarization out of specularly reflected light from the pattern, and an image forming means for forming an image of the surface of the substrate based on the extracted light. A pattern forming condition in the pattern forming process is specified based on the light intensity of the image of the surface of the substrate formed by the image forming means.

Abstract: A method of adjusting optical imaging system is provided to finely adjust arrangement of optical elements with sensitivity. Illumination light with a predetermined wavelength band is irradiated to an adjustment mark including first marks disposed at a first pitch and second marks disposed at a second pitch different from the first pitch. An image is captured according to light, of diffracted light emitted from the adjustment mark, passing through an aperture stop and reaching an image surface of the optical imaging system. A positional deviation between the first and second marks is calculated with symmetric/asymmetric property of luminance information. Based on respective positional deviations calculated while the wavelength band of illumination light is changed, arrangement of optical elements between a pupil plane and an aperture stop surface of the optical imaging system is finely adjusted, to correct imaging positional deviation of a pupil image on the aperture stop surface.

Abstract: A mirror rotation angle detection mechanism is provided for an optical system having a mirror which is rotatable about an axis substantially on a reflection surface thereof at which a main beam of light is reflected. The mirror has a thin reflective layer with opposite surfaces that are nearly coplanar, and one of which constitutes the main beam reflection surface. The detection mechanism includes a light emitting member to irradiate a beam of detection light onto the opposite surface of the reflective layer. A light receiving element recieves the reflected detection beam, and an angle detection circuit detects the rotation angle of the mirror in accordance with the output of the light receiving element. According to a preferred embodiment, a condenser lens may be arranged between the light emitting member and the detection beam reflection surface.
