Semiconductor light emitting element and method for manufacturing the same

摘要

A semiconductor light emitting element includes a substrate and a stacked body. The stacked body is aligned with the substrate. The stacked body includes first and second semiconductor layers, a light emitting layer, and first and second electrodes. The first semiconductor layer has a first face including first and second portions. The first portion is provided with a plurality of convex portions. The second portion is aligned with the first portion. The second semiconductor layer is provided facing the second portion. The light emitting layer is provided between the second portion and the second semiconductor layer. The second semiconductor layer is disposed between the second electrode and the light emitting layer. An interval of each of the convex portions is no less than 0.5 times and no more than 4 times a wavelength of a light emitted from the light emitting layer.

1. A semiconductor light emitting element, comprising:
a first semiconductor layer of a first conductivity type, the first semiconductor layer includes a first region and a second region; a second semiconductor layer of a second conductivity type, the second semiconductor layer being apart from the second region in a first direction, the first direction crossing a direction from the first region toward second region; a light emitting layer provided between the second region and the second semiconductor layer in the first direction, the light emitting layer being configured to emit light having a wavelength; and a first electrode electrically connected with the first semiconductor layer, the first region having a first face being provided with a plurality of convex portions, the first electrode overlapping the convex portions in the first direction, a distance in a second direction between a first center and a second center being not less than 0.5 times and not more than 4 times the wavelength, the second direction being perpendicular to the first direction, the first center being a center of one of the convex portions in the second direction, the second center being a center of another one of the convex portions in the second direction, the another one of the convex portions being most proximal to the one of the convex portions among the convex portions.
