  • Patent number: 8098363
    Abstract: An exposure apparatus that exposes a shot region on a substrate to radiant energy based on an obtained position of a surface of the shot region. A projecting optical system obliquely projects detection light to a surface of a shot region on a substrate. A receiving optical system receives the detection light reflected at the shot region. A detector includes a photodetector that accumulates charges generated by the detection light incident thereon and detects a position of the detection light incident on the photodetector from the receiving optical system. A controller obtains a position of the surface based on the detection by the detector.

  • Publication number: 20090115888
    Abstract: An exposure apparatus according to this invention comprises a detector configured to obliquely project detection light to a surface of a substrate and to detect a position of the surface based on the detection by the detector, and exposes the substrate to radiant energy based on the calculated position of the light. The controller is configured to correct, to obtain the calculated position of the surface, a position of the surface calculated based on the detection by the detector, in accordance with a period before the detection, during the period the detector being in a dark state in which the detection light is not incident on the detector.
