Abstract

The invention discloses a high-voltage light-emitting diode and a manufacturing method thereof. In the structures of the high-voltage light-emitting diode, a transparent insulating layer, a part of atransparent current expanding layer and a transparent conducting layer are arranged between the adjacent light-emitting structures; the transparent insulating layer, the part of the transparent current expanding layer and the transparent conducting layer are all of light-permeable structures, so that the light-emitting areas of the side edges of the light-emitting structures are enlarged, and thelight-emitting efficiency of the high-voltage light-emitting diode is improved; and the transparent conducting layer is in contact with the transparent current expanding layer, and the transparent conducting layer is made of metal, so that the resistance of the transparent current expanding layer can be reduced, the current expanding effect is improved, and the light-emitting efficiency of the high-voltage light-emitting diode is further improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor devices, and more specifically, to a high-voltage light-emitting diode and a manufacturing method thereof. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor electronic device that converts electrical energy into light energy. When current flows, electrons and holes recombine within it to emit light. As a new type of high-efficiency, environmentally friendly, and green solid-state lighting source, LED has the advantages of low voltage, low power consumption, small size, light weight, long service life, and high reliability. It is being widely used in various fields; such as transportation Signal lights, automotive interior and exterior lights, urban landscape lighting, mobile phone backlight, display screens, etc., especially in the field of lighting, high-power chips are the future development trend of LEDs. [0003] In the field of semicon...
