摘要： A semiconductor light emitting device has a semiconductor laminate including first and second conductivity type semiconductor layers respectively providing first and second main surfaces and an active layer. The semiconductor laminate is divided into first and second regions. At least one contact hole is formed to pass through the active layer from the second main surface of the first region. A first electrode is formed on the second main surface to be connected to the first conductivity type semiconductor layer of the first region and the second conductivity type semiconductor layer of the second region. A second electrode is formed on the second main surface of the first region to be connected to the second conductivity type semiconductor layer of the first region and the first conductivity type semiconductor layer of the second region.

摘要： Disclosed are a light emitting diode (LED) inspection apparatus, which can determine whether an LED has a defect such as leakage current, without making physical contact with the LED being inspected, and an LED inspection method thereof. The LED inspection apparatus includes an ultraviolet emission unit emitting UV light to an LED, an image generation unit generating an image of the LED to which the UV light is emitted, and a control unit obtaining color or intensity information of the LED from the image of the LED and determining, based on the color information, whether the LED is defective
