LED (Light-Emitting Diode) chip with pyramid array structure and manufacturing method thereof

The invention discloses an LED (Light-Emitting Diode) chip with a pyramid array structure and a manufacturing method thereof. The LED (Light-Emitting Diode) chip with the pyramid array structure comprises a transparent substrate with an epitaxial layer; the surface of the top part of the transparent substrate is of the pyramid array structure; the bottom part of the transparent substrate is the epitaxial layer, the bottom part of the epitaxial layer is the anode and the cathode of a chip electrode; and the pyramid array structure is formed by mutually staggering V-shaped groove arrays. The LED chip has the beneficial effects that the specific surface area is larger, so that a vaporization core can be greatly increased; the vaporization process in the boiling process is favorably evaporated, so that the chip has excellent boiling and heat exchange strengthening capacities, and the processing efficiency of the chip is greatly improved; and the processing process is simple, and the cost is low.
