Horizontal light emitting diode and manufacturing method thereof

Abstract

The invention discloses a horizontal light emitting diode and a manufacturing method thereof. The horizontal light emitting diode comprises a luminous lamination layer, a transparent conductive layer, a high reflection layer, an electrical communicating channel and two nail line electrode layers, wherein the transparent conductive layer covers the luminous lamination layer; the high reflection layer is formed on one side of the transparent conductive layer far from the luminous lamination layer; the electrical communicating channel passes through the luminous lamination layer to the transparent conductive layer; and one of the two nail line electrode layers is arranged on one side of the luminous lamination layer without the transparent conductive layer, the other one is electrically connected with the transparent conductive layer through the electrical communicating channel, and voltage drop is formed between the two nail line electrode layers. The electrical communicating channel can be in contact with the transparent conductive layer without aligning, so that the horizontal light emitting diode can be easily manufactured and forward bias can be reduced; and the transparent conductive layer can be transmitted by light and the light is totally reflected by the high reflection layer, so that the light emitting efficiency can be increased to meet the requirements.

Description

technical field [0001] The invention relates to a light emitting diode, in particular to a horizontal light emitting diode, and also to a manufacturing method of the horizontal light emitting diode. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a kind of luminescent light-emitting element. Its light-emitting principle is to apply a current to the III-V compound semiconductor material, and use the combination of electrons and holes in the diode to convert energy into the form of light. , it can emit light when the energy is released, and it will not be as hot as an incandescent bulb after a long time of use. The advantages of light-emitting diodes are small size, long life, low driving voltage, fast response rate, and excellent shock resistance. They can meet the needs of light, thin, and miniaturized equipment, and have become very popular products in daily life. [0003] The current luminous performance and efficiency of light-emitting...

Problems solved by technology

However, the P-type ohmic contact metal electrode layer 7 is distributed on the mirror protective layer 8 in a sheet shape, so the position of the P-type ohmic contact metal electrode layer 7 needs to be determined by an alignment technique, and the manufacturing process is rather cumbersome, and When the overall structure is distorted, it will cause more difficulties in alignment. In addition, the P-type ohmic contact metal electrode layer 7 is a light-absorbing material, which will also reduce the overall luminous efficiency.
