    摘要: Position-detection apparatus (alignment sensors) are disclosed for determining the position of an object (e.g., wafer, bearing a position-detection mark) as required in microlithography processes for manufacturing semiconductor devices and displays. The apparatus comprises an irradiation optical system, a condenser optical system, a first photoelectric detector, a fiducial body bearing a fiducial mark, a combining optical system, a second photoelectric detector, and a processor. The position-detection and fiducial marks are illuminated with coherent illumination light from the irradiation optical system. Light diffracted from the marks is condensed by the condenser optical system. The first photoelectric detector receives the condensed diffracted light and produces first electrical signals. The combining optical system receives the diffracted light from the fiducial mark. The second photoelectric detector receives multiple diffracted light beams from the fiducial mark and produces second electrical signals. From the electrical signals, the processor determines the position of the position-detection mark relative to the fiducial mark.

    摘要: An image detection apparatus (10) having an illumination system (IS) irradiates light onto the surface (30S) of an object 30 to be inspected for defects. A detection optical system (34) condenses the light from the surface and forms an image of the surface on an image detector (48). The detection optical system includes a receiving mirror (38) having an optical axis (A.sub.38) that intersects the reference optical axis (A.sub.34) of the detection optical system. A processing apparatus (60) includes a processing system (62) that performs image processing based on an output from the detector corresponding to the image. The processing system includes an image distortion correction unit (62a) for eliminating the effects of distortion in the image of the surface generated by the inclination of the surface with respect to the reference optical axis and the receiving mirror.
