Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] As mentioned in the background art, traditional light-emitting diodes generally work under direct current, and the voltage of a single LED chip is generally between 2-4V. In practical applications, especially in high-power light sources, it is generally implemented in series. For example, in the packaging process, a lamp bead uses multiple LED chips in series, or in the lamp assembly process, a light-emitting module uses multiple lamp beads. in series. ...

Abstract

The invention discloses a high-voltage light-emitting diode with a double-sided horizontal bridging structure and a manufacturing method of the high-voltage light-emitting diode. According to the invention, by means of a first series electrode and a second series electrode, the connection of a first type semiconductor layer and a second type semiconductor layer above and below an epitaxial structure is realized. Finally, the serial connection between different light emitting structures is realized. Moreover, a horizontal bridging structure is realized due to the fact that the first serial electrode and the second serial electrode have no large height difference. As a result, the conditions of short circuit and open circuit in the process of manufacturing the high-voltage light emitting diode are improved. The reliability of the high-voltage light-emitting diode is further improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor devices, more specifically, to a high-voltage light-emitting diode with a double-sided horizontal bridge structure and a manufacturing method thereof. Background technique [0002] Light Emitting Diode (English: Light Emitting Diode, referred to as: LED), as a very influential new product in the optoelectronics industry, has the characteristics of small size, long service life, colorful colors, low energy consumption, energy saving and environmental protection, and high safety. Another leap in the history of human lighting after incandescent lamps and fluorescent lamps is driving the upgrading of traditional lighting and display industries. It is widely used in lighting, display screens, signal lights, backlights, toys and other fields. [0003] Traditional light-emitting diodes generally work under direct current, and the voltage of a single LED chip is generally between 2-4V. In practical...
