    • The invention relates to a high-output nitride light emitting device. The light emitting device includes a first conductivity type nitride semiconductor layer, an active layer and a second conductivity type nitride semiconductor layer deposited in their order on a substrate. The light emitting device also includes first and second insulation layers formed in different upper surface portions of the nitride semiconductor light emitting device, and first and second bonding pads formed respectively on the first and second insulation layers. The light emitting device further includes first and second extension electrodes extended from the first and second bonding pads and coupled respectively to the first and second conductivity semiconductor layers. The electrode arrangement according to the present invention prevents direct coupling between the bonding pads and the light emitting device, thus allowing a symmetrical structure that can achieve more uniform current spreading using only the extension electrodes.
    • 本发明涉及高输出氮化物发光器件。 发光器件包括依次沉积在衬底上的第一导电型氮化物半导体层,有源层和第二导电型氮化物半导体层。 发光器件还包括形成在氮化物半导体发光器件的不同上表面部分中的第一和第二绝缘层,以及分别形成在第一绝缘层和第二绝缘层上的第一和第二接合焊盘。 发光器件还包括从第一和第二焊盘延伸并分别耦合到第一和第二导电半导体层的第一和第二延伸电极。 根据本发明的电极装置防止接合焊盘和发光器件之间的直接耦合,从而允许仅使用延伸电极实现更均匀的电流扩展的对称结构。
