Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a light emitting diode chip and a preparation method thereof. Background technique [0002] Light Emitting Diode (English: Light Emitting Diode, referred to as: LED) is a semiconductor light emitting device made by using the principle of semiconductor PN junction electroluminescence. The primary product in the preparation process of the light-emitting diode is an epitaxial wafer. The epitaxial wafer and electrodes fabricated on the epitaxial wafer form a light-emitting diode chip, and the light-emitting diode chip is arranged on a heat dissipation base to form a light-emitting diode chip. [0003] Gallium nitride (GaN) has good thermal conductivity, and has excellent characteristics such as high temperature resistance, acid and alkali resistance, and high hardness, so that gallium nitride (GaN)-based LEDs have received more and more attention and research. The current pre...
