  • Publication number: 20120125169
    Abstract: A movable stage on which an LED chip is placed is moved in horizontal directions (for example, the x-axis direction and the y-axis direction) under the control of a position adjusting section. A probe needle is brought into contact with a bonding electrode on the surface of the LED chip to apply a desired voltage to the LED chip. A light detecting section detects light from the LED chip. An optical characteristic measuring section measures, based on the results of detection by the light detecting section, optical characteristics of the LED chip. A laser light source removes a part of the surface of the LED chip by laser light.

  • Publication number: 20110284883
    Abstract: Provided is a light-emitting element in which two LED structures are dividedly formed on a rectangular substrate. The LED structures are each a semiconductor layer made by laminating an n-type semiconductor layer (a LED structure), an active layer (not shown), and a p-type semiconductor layer, and are respectively provided near both ends of a diagonal line of the upper surface of the substrate. On the upper surface of the substrate, two bonding electrodes each having a circular surface are also respectively formed near both ends of the other diagonal line, and two resistance elements each formed of the n-type semiconductor layer are respectively provided near two opposite sides of the substrate.
