    • A nitride semiconductor light-emitting device with an electron pattern that applies current uniformly to an active layer to improve light emission efficiency is provided. The nitride semiconductor light-emitting device includes multiple layers of a substrate, an n-type nitride layer, an active layer of a multi-quantum-well structure, and a p-type nitride layer. The nitride semiconductor light-emitting device further includes a p-electrode pattern and an n-electrode pattern. The p-electrode pattern includes one or more p-pads disposed on the p-type nitride layer, and one or more p-fingers extending from the p-pads. The n-electrode pattern includes one or more n-pads disposed on an exposed region of the n-type nitride layer to correspond to the p-pads, and one or more n-fingers extending from the n-pads. The n-fingers have identical resistance, and the p-fingers have identical resistance to improve current spreading to the active layer.
    • 提供了具有均匀地向有源层施加电流以提高发光效率的电子图案的氮化物半导体发光器件。 氮化物半导体发光器件包括多层衬底,n型氮化物层,多量子阱结构的有源层和p型氮化物层。 氮化物半导体发光器件还包括p电极图案和n电极图案。 p电极图案包括设置在p型氮化物层上的一个或多个p焊盘以及从p焊盘延伸的一个或多个p指。 n电极图案包括设置在n型氮化物层的暴露区域上以对应于p焊盘的一个或多个n焊盘以及从n焊盘延伸的一个或多个n指。 n指具有相同的电阻,并且p指具有相同的电阻以改善向有源层的电流扩展。
