Patent ID: 8628983

Claim:
A method of fabricating a light emitting diode, the method comprising: forming semiconductor layers on a first substrate, the semiconductor layers comprising a buffer layer, a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer; forming a metal pattern on the second conductive type semiconductor layer; forming a bonding metal layer on a second substrate; bonding the metal pattern and the bonding metal layer; separating the first substrate from the semiconductor layers; patterning the semiconductor layers, the metal pattern, and the bonding metal layer to form separated metal patterns and light emitting cells arranged on at least one region of the respective separated metal patterns; and dicing the second substrate to form individual light emitting diode chips, wherein the second substrate is homogeneous with the first substrate, and wherein the separating of the first substrate from the semiconductor layers comprises irradiating light onto a side of the first substrate to decompose the buffer layer formed on an opposite side of the first substrate.
