LIGHT-EMITTING DIODE STRUCTURE AND PREPARATION METHOD THEREFOR

摘要

A light-emitting diode structure and the preparation method therefor. Using a secondary growing manner, an aluminum nitride layer is made and inserted, stops the defects extension of a bottom layer and improves wafer warpage phenomena caused by thermal reaction; meanwhile, patterning treatment is performed on the aluminum nitride layer so as to improve the light emitting efficiency of the light-emitting diode.
