Abstract: A semiconductor light emitting device includes: first and second conductive type semiconductor layers; an active layer disposed between the first and second conductive type semiconductor layers; and first and second electrodes disposed on one surface of each of the first and second conductive type semiconductor layers, respectively, wherein at least one of the first and second electrodes includes a pad part and a finger part formed to extend from the pad part, and the end of the finger part has an annular shape. Because a phenomenon in which current is concentrated in a partial area of the finger part is minimized, tolerance to electrostatic discharge (ESD) can be strengthened and light extraction efficiency can be improved.

Abstract: An n-type GaN layer is formed on a substrate, and an active layer is formed on the n-type GaN layer. A p-type GaN layer is formed on the active layer, and portions of the p-type GaN layer and the active layer are mesa-etched so as to expose a portion of the n-type GaN layer. An irregularities forming layer is formed on the p-type GaN layer and a photosensitive film pattern for forming a surface irregularities pattern is formed on the irregularities forming layer. The irregularities forming layer is selectively wet-etched by using the photosensitive film pattern as an etching mask, thereby forming surface irregularities. A p-electrode is formed on the p-type GaN layer having the surface irregularities formed thereon, and an n-electrode is formed on the exposed n-type GaN layer.”

Abstract: In a semiconductor light emitting device, a light emitting structure includes a first-conductivity type semiconductor layer, an active layer, and a second-conductivity type semiconductor layer, which are sequentially formed on a conductive substrate. A second-conductivity type electrode includes a conductive via and an electrical connection part. The conductive via passes through the first-conductivity type semiconductor layer and the active layer, and is connected to the inside of the second-conductivity type semiconductor layer. The electrical connection part extends from the conductive via and is exposed to the outside of the light emitting structure. An insulator electrically separates the second-conductivity type electrode from the conductive substrate, the first-conductivity type semiconductor layer, and the active layer. A passivation layer is formed to cover at least a side surface of the active layer in the light emitting structure. An uneven structure is formed on a path of light emitted from the active layer.
