Abstract

The invention relates to a semiconductor photoelectric structure for improving light extraction efficiency and a manufacturing method thereof. The semiconductor photoelectric structure comprises a substrate and a buffer layer positioned on the substrate, wherein the buffer layer is provided with a continuous hole pattern between the buffer layer and the substrate; a semiconductor layer is positioned on the buffer layer, and comprises an n-type conduction layer positioned on the buffer layer, a light emitting layer positioned on the n-type conduction layer, a p-type conduction layer positionedon the light emitting layer, a transparent electrically-conductive layer positioned on the semiconductor layer, a p-type electrode positioned on the transparent electrically-conductive layer, and an n-type electrode positioned on the n-type conduction layer. Continuous holes are formed below the light emitting layer to reflect the light emitted by the light emitting layer, so that the light intensity and luminance of a light emitting surface are improved. In addition, the defect density of an epitaxy can be reduced, and the quality of the epitaxy can be improved.

Description

technical field [0001] The invention relates to a structure of a group III nitride semiconductor light-emitting element and a manufacturing method thereof, in particular to a structure for improving light extraction rate and a manufacturing method thereof. Background technique [0002] The traditional light-emitting diode structure is limited by total reflection and transverse waveguide effect, so it is impossible to take out all the light generated by the light-emitting layer, and some of it will be absorbed by internal components such as active layer, buffer layer, material defects, and metal electrodes, making the light-emitting diode as a whole The light extraction rate is low. [0003] Taking the blue-white gallium nitride (GaN) group III nitride light-emitting diode as an example, the refractive index of gallium nitride (GaN) is 2.5, and the refractive index of air is 1. Assuming that the light is emitted on a uniform optical surface, it can be calculated The critical...
