  • Patent number: 9425036
    Abstract: Provided are a light source device and a semiconductor manufacturing apparatus including the same. The light source device includes a light-emitting lamp. The light source device includes a laser generator configured to generate and direct a laser beam to the light-emitting lamp. The light source device includes a recycling optical element configured to redirect the laser beam to the light-emitting lamp. The recycling optical element includes a first recycling optical modulator configured to change the phase of the laser beam.

  • Patent number: 9255694
    Abstract: An illumination optic system includes a convex mirror to reflect light from a light source to towards a lens. The light source is at a first focus position and the lens is at a second focus position of the mirror. The system also includes a reflector to reflect light not incident on the lens toward the convex mirror. The reflector has a light guide hole to guide light to the incidence surface of the lens.

  • Patent number: 8841824
    Abstract: A broadband light illuminator of an optical inspector for optically detecting defects of an inspection object may include an electrode-less chamber including a plasma area from which broadband light is generated; a first energy provider, exterior to the chamber, configured to provide first energy for ionizing high pressure gases to form ionized gases in the chamber; a second energy provider, exterior to the chamber, configured to provide second energy for transforming the ionized gases into a plasma state to form the plasma area at a central portion of the chamber; an elliptical reflector having a first focus at which the chamber is positioned and a second focus such that the broadband light is reflected from the elliptical reflector toward the second focus; and a lens unit focusing the reflected broadband light onto the inspection object to form an inspection light for detecting the defects of the inspection object.

  • Patent number: 7166856
    Abstract: An apparatus and method to inspect a display panel that can correctly detect a defect of the display panel itself. In the method of inspecting the display panel, a first image is captured from the display panel in a state in which no pattern is applied to the display panel. Light is then irradiated on the display panel in a state in which a pattern is applied to the display panel, and a second image is captured from the display panel. The first image can be compared with the second image, and a determination can be made as to whether or not a defect of the display panel is present.
