    摘要: A semiconductor light emitting device having a multiple pattern structure greatly increases light extraction efficiency. The semiconductor light emitting device includes a substrate and a semiconductor layer, an active layer, and an electrode layer formed on the substrate, a first pattern defining a first corrugated structure between the substrate and the semiconductor layer, and a second pattern defining a second corrugated structure on the first corrugated structure of the first pattern.
