  • Publication number: 20110303938
    Abstract: A group III nitride semiconductor light-emitting element having improved light extraction efficiency is provided. The light-emitting element has a plurality of dot-like grooves formed on a surface at the side joining to a p-electrode of a p-type layer. The groove has a depth reaching an n-type layer. Side surface of the groove is slanted such that a cross-section in an element surface direction is decreased toward the n-type layer from the p-type layer. Fine irregularities are formed on the surface at the side joining to an n-electrode of the n-type layer, except for a region on which the n-electrode is formed, and a translucent insulating film having a refractive index of from 1.5 to 2.3 is formed on the fine irregularities. Light extraction efficiency is improved by reflection of light to the n-type layer side by the groove and prevention of reflection to the n-type layer side by the insulating film.
