Abstract: A high-voltage light emitting diode and fabrication method thereof, in which, the liquid insulating material layer/the liquid conducting material layer, after curing, is used for insulating/connecting, making the isolated groove between the light emitting units extremely narrow (opening width≦0.4 μm, such as ≦0.3 μm), which improves single chip output, expands effective light emitting region area and improves light emitting efficiency; the serial/parallel connection yield is improved for this method avoids easy disconnection of wires across a groove with extremely large height difference in conventional high-voltage light emitting diodes; in addition, the manufacturing cost is reduced for the LED can be directly fabricated at the chip fabrication end.

Abstract: A bonding electrode structure of a flip-chip LED chip includes: a substrate; a light-emitting epitaxial layer over the substrate; a bonding electrode over the light-emitting epitaxial layer, wherein the bonding electrode structure includes a metal laminated layer having a bottom layer and an upper surface layer from bottom up. The bottom layer structure is oxidable metal and the side wall forms an oxide layer. The upper surface layer is non-oxidable metal. The bonding electrode structure has a main contact portion, and a grid-shape portion surrounding the main contact portion in a horizontal direction. The problems during packaging and soldering of the flip-chip LED chip structure, such as short circuit or electric leakage, can thus be solved.
