The present disclosure discloses a method for preparing a light-emitting diode epitaxial wafer and an epitaxial wafer with improved internal quantum efficiency, and belongs to the field of light-emitting diode production. During the first stage of the growth of the InGaN well layer, the indium source flow rate is linearly increased to the first indium source threshold, and the gallium source is linearly reduced from the first gallium source threshold to the second gallium source threshold, so that an In source enriched region can be formed within the thickness of the thin InGaN well layer in a short time, thereby improving the light extraction efficiency of the multi-quantum well layer. The second stage of growth plays a role in transition and improving the crystal quality. In the third stage, the indium source remains unchanged while the gallium source increases linearly, and in the fourth stage, both the indium source and the flow rate are increased to improve the luminous efficiency. In the fifth and sixth stages, the enrichment of In is further reduced, thereby improving the overall quality. The changes in the enrichment degree of In in the six stages relieve the polarization electric field, increase the overlapping area of ​​the electron-hole wave function, and improve the internal quantum efficiency of the light-emitting diode.

The present application relates to an anti-fuse structure and a preparation method thereof, as well as an editable memory including the anti-fuse structure. The anti-fuse structure includes: a first doping region and a second doping region at least partially formed in the first doping region; an isolation layer formed on the first doping region and part of the second doping region, the isolation layer having a window exposing the second doping region; a gate structure including a stacked fuse dielectric layer and a gate conductive layer, the fuse dielectric layer contacting the second doping region through the window; a first electrode contacting the gate conductive layer; a second electrode sequentially penetrating the gate structure and the isolation layer and contacting the second doping region, the second electrode and the gate structure being electrically isolated by an isolation pad. By arranging the second doping region below the gate structure and allowing the second electrode to penetrate the gate structure to contact the second doping region, the area occupied by the anti-fuse structure can be reduced and the integration of the device can be improved.
