Abstract

A method for producing an LED includes the following steps: a. forming an anode electrode on a transparent base board, and forming an anode electrode pattern; b. forming a first insulation layer on the anode electrode; c. forming a layer of silicon nanometer points on the first insulation layer; d. forming a layer of silicon carbide nanometer points on the silicon nanometer points; e. performing heat treatment so as to enable the silicon nanometer points and the silicon carbide nanometer points to diffuse into a layer of uniformly mixed silicon carbide alloy nanometer points; f. forming a second insulation layer on the layer of the silicon carbide alloy nanometer points; and g. forming a cathode electrode on the second insulation layer, and forming a cathode electrode pattern.

Description

【Technical field】 [0001] The invention relates to a light emitting diode and a manufacturing method thereof. 【Background technique】 [0002] In recent years, the optoelectronic industry has developed. Light Emitting Diodes (LEDs) have been widely used in display devices and optical read-write devices due to their advantages of small size, low energy consumption, high brightness, long life and stable light emission. [0003] In the production of light-emitting diodes, since the compound semiconductor is a direct bandgap semiconductor (Direct Semiconductor), it has better luminous efficiency, so the compound semiconductor is mainly used at present. However, the cost of compound semiconductors is significantly higher than that of group IV semiconductors (C, Si, Ge), so the industry is studying how to use group IV semiconductors to make light-emitting diodes. Group IV semiconductors are Indirect Semiconductors. In the theory of luminescence, because it is difficult to obey the ...
