Abstract:
The present invention relates to an LED die package, which has a light-emitting diode die having a sapphire layer, a first doped layer doped with a p- or n-type dopant, and a second doped layer doped with a different dopant from that doped in the first doped layer. A surface of the sapphire layer opposite to the surface on which the first doped layer is disposed is formed with generally inverted-pyramidal-shaped recesses and overlaid with a phosphor powder layer. Each of the first and the second doped layers has an electrode-forming surface formed with an electrode, on which an insulation layer is disposed and formed with exposure holes for exposing the electrodes. The exposure holes are each filled with an electrically conductive linker.
