摘要： A semiconductor light emitting device includes a first conductivity-type semiconductor layer, an active layer and a second conductivity-type semiconductor layer sequentially stacked on a substrate. A first electrode is disposed on a portion of the first conductivity-type semiconductor layer. A current diffusion layer is disposed on the second conductivity-type semiconductor layer and includes an opening exposing a portion of the second conductivity-type semiconductor layer. A second electrode covers a portion of the current diffusion layer and the exposed portion of the second conductivity-type semiconductor layer, wherein the portion of the current diffusion layer is near the opening.

摘要： A testing apparatus includes a plate unit including at least one chip mounting unit on which a light emitting diode (LED) to be tested is mounted. The chip mounting unit has a first region in which the LED is overlaid and a second region surrounding the first region. The first and second electrode pads are disposed in the first region and include respective extension portions extended toward the second region. A probe portion is configured to connect to the extension portions of the first and second electrode pads. A power control unit is configured to selectively apply test power to the LED through the probe portion. A light measuring unit is configured to measure light properties of light emitted by the LED.
