LIGHT EMITTING DIODE AND A MANUFACTURING METHOD THEREOF, A LIGHT EMITTING DEVICE

摘要

An LED includes a first electrode, for connecting the LED to a negative electrode of a power supply and a substrate located on the first electrode in which a plurality of contact holes are formed extending through the substrate. The diameter of upper parts of the contact holes is less than the diameter of lower parts of the contact holes, and the contact holes are filled with electrode plugs connecting the first electrode to the LED die. The light emitting device includes the LED, and further includes a susceptor and an LED mounted on the susceptor. The manufacturing method includes forming successively an LED die and a second electrode on a substrate, patterning a back surface of the substrate to form inverted trapezoidal contact holes which expose the LED die, and filling the contact holes with conductive material until the back face of the substrate is covered by the conductive material.
