Abstract:
1. A GaN light emitting diode suitable for flip-chip bonding, said diode comprising: a sapphire substrate; a light emitting structure including a first GaN clad layer, an activation layer, and a second GaN clad layer sequentially formed on the sapphire substrate, said first GaN clad layer being exposed at one or more portions thereof, the exposed portions of the first GaN clad layer being in the shape of a line with a predetermined width; a plurality of first electrodes and a second electrode respectively formed on the exposed portions of the first GaN clad layer and on the second GaN clad layer, said first electrodes and second electrode being in the shape of lines parallel to each other; a passivation layer being formed on the light emitting structure and the first and second electrodes to protect the first and second electrodes and the light emitting structure and being punched at portions thereof; and a first bonding electrode and a second bonding electrode formed on the passivation layer so as to be insulated from each other and respectively connected to the first and second electrodes through the punched portions of the passivation layer.
