Abstract
Disclosed are a light emitting structure and a preparation method therefor. The method includes: forming a mask layer on a n-type substrate, disposing a plurality of openings in the mask layer; and forming a light emitting unit in each of the plurality of openings, including: forming a metal atomic layer in the opening; forming an n-type semiconductor layer on the metal atomic layer, and forming a light extraction structure on the n-type semiconductor layer; and sequentially forming an active layer and a p-type semiconductor layer on the n-type semiconductor layer and the light extraction structure. In this way, step of peeling off the substrate may be avoided. In addition, with a plurality of discrete light emitting structures formed on the same substrate, a step of cutting a device is avoided, and damage to the device can be prevented.
