Abstract

The invention discloses an integrated LED element with an epitaxial structure integrated with a packaging substrate and a manufacturing method. An LED element is formed by directly forming an LED epitaxial structure, electrodes, wires, etc. on a substrate to become an independent integrated LED element. . The LED element is a polycrystalline module structure, and can also be a single crystal structure. The LED element can be embedded in a bare empty carrier body, and through the support of the bare empty carrier body, the lower surface of the substrate of the LED element can be directly placed and contacted on a heat conduction or heat dissipation element. The LED element is directly fabricated on the wafer and cut into an independent element. The structure of the LED element can be a vertical structure or a horizontal structure according to different manufacturing methods.

Description

technical field [0001] The present invention relates to an integrated LED element that combines an epitaxial structure and a packaging substrate and a manufacturing method thereof, in particular, relates to directly using the carrying substrate carrying the LED epitaxial structure as a packaging substrate, and packaging the original LED grain The process completes the LED element on the substrate, so that the substrate can be directly placed and contacted with a heat conduction or heat dissipation element when the LED element is applied. The integrated LED element is manufactured directly on the wafer and then cut to become an independent element, and LED elements with a vertical structure or a horizontal structure can be produced according to different processes. Background technique [0002] For the LED lighting industry, the general product and industrial division of labor mode is to separate the production of LED grains and LED packaging into two completely independent p...
