Abstract:
Provided is a light emitting diode (LED) mounted on a carrier substrate and including a semiconductor epitaxial structure and at least one electrode pad structure. The semiconductor epitaxial structure is electrically connected to the carrier substrate. The electrode pad structure includes a eutectic layer, a barrier layer and a ductility layer. The eutectic layer is adapted for eutectic bonding to the carrier substrate. The barrier layer is between the eutectic layer and the semiconductor epitaxial structure. The barrier layer blocks the diffusion of the material of the eutectic layer in the eutectic bonding process. The ductility layer is between the eutectic layer and the semiconductor epitaxial structure. The ductility layer reduces the stress on the LED produced by thermal expansion and contraction of the substrate during the eutectic bonding process, so as to prevent the electrode pad structure from cracking, and maintain the quality of the LED.

Claim (Index 7):
The light emitting diode of  claim 6 , wherein the eutectic layer comprises at least one material selected from the group consisting of Au, Au/Sn and Sn/Ag/Cu.
