| titleOfInvention | Light-emitting diodes and light-emitting devices |
| abstract | The present invention relates to the field of semiconductor manufacturing technology, in particular to a light emitting diode, which includes an epitaxial structure, a first electrode and a second electrode, the epitaxial structure has opposite first surfaces and second surfaces, and the epitaxial structure includes an N-type semiconductor layer, A light-emitting layer and a P-type semiconductor layer, the light-emitting layer is located between the N-type semiconductor layer and the P-type semiconductor layer, the P-type semiconductor layer includes a P-type contact layer and a P-type base layer, and the P-type base layer is located between the P-type contact layer and the light-emitting layer , the first electrode is located on the second surface of the epitaxial structure and is electrically connected to the N-type semiconductor layer, and the second electrode is located on the second surface of the epitaxial structure and is electrically connected to the P-type semiconductor layer, wherein the doped P in the P-type contact layer The impurity concentration of the type decreases gradually along the direction from the first surface to the second surface. Thereby, the luminous efficiency of the light-emitting diode can be effectively improved, and the aspect of aging and light decay can also be significantly improved. |
