Problems solved by technology

[0004] The above-mentioned previous proposal uses a metal permanent substrate to replace the sapphire substrate to improve the problem of poor thermal conductivity and achieve antistatic effects. However, the metal permanent substrate is made of metal materials, which can help heat conduction, but it also improves the performance of LEDs. production cost
[0005] It can be seen that the above-mentioned existing manufacturing method for forming a light-emitting diode with a metal substrate obviously still has

Abstract

The invention relates to a method for manufacturing a light-emitting dioxide having a thermally and electrically conductive substrate and a structure thereof. The manufacturing method comprises the following steps of: providing a first substrate; forming a light emitting epitaxial layer on the first substrate; combining a second substrate on a first surface of the light emitting epitaxial layer; removing the first substrate; and forming an electrode. The structure of the light-emitting dioxide having the thermally and electrically conductive substrate comprises the second substrate, the light emitting epitaxial layer and the electrode. A used thermally conducive and insulating substrate material with high thermal conductivity allows the heat generated by the light-emitting dioxide during light emission to be discharged effectively to stabilize the quality of emitted light; and a used nonmetal thermally conductive and insulating substrate material results in the reduction of the manufacturing cost of the light-emitting dioxide.

Description

technical field [0001] The invention relates to a method for manufacturing a light-emitting diode with a conductive and heat-conducting substrate and its structure, in particular to a method for manufacturing a light-emitting diode with a conductive and heat-conducting substrate and its structure. Background technique [0002] In conventional light-emitting diodes using sapphire substrates, the heat generated by the light-emitting diodes cannot be effectively removed due to the poor thermal conductivity of the sapphire substrates, which reduces the light-emitting efficiency of the light-emitting diodes and shortens the service life of the light-emitting diodes. Moreover, the sapphire substrate has a non-conductive characteristic, so the problem of static electricity accumulation is prone to occur. [0003] As disclosed in Taiwan Patent No. I224876 "Manufacturing Method for Forming a Light Emitting Diode with a Metal Substrate", it includes the following steps: providing a te...
