  • Publication number: 20220254955
    Abstract: A light emitting diode structure includes a metal reflective layer, a first transparent electrically-conductive layer, a dielectric layer, second transparent electrically-conductive layers, a first type semiconductor layer, an active layer and a second type semiconductor layer. The metal reflective layer has first concave sections. The first transparent electrically-conductive layer is conformally formed over the first concave sections of the metal reflective layer. The dielectric layer is formed over the first transparent electrically-conductive layer and has through holes to expose the first transparent electrically-conductive layer. The second transparent electrically-conductive layers are formed over the dielectric layer, and connected with the first transparent electrically-conductive layer via the through holes. Each second transparent electrically-conductive layer is connected to the first transparent electrically-conductive layer to form a T-shaped cross section in each first concave section.

  • Patent number: 10297733
    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 ?m, such as ?0.3 ?m), 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.
