| abstract |
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. |
