Flip-chip light emitting diode and fabricating method thereof
A flip-chip light emitting diode and fabricating methods are disclosed. A soft transparent adhesive layer is utilized to past a transparent conductive substrate onto a light emitting diode epitaxy structure on a substrate, and the substrate is next removed entirely. Then, a mesa-etching process is performed to form a first top surface and a second top surface on the light emitting diode epitaxy structure for respectively exposing an n-type layer and a p-type layer in the light emitting diode epitaxy structure. Next, a metal reflective layer and a barrier layer are formed on the light emitting diode epitaxy structure in turn, and electrodes are finally fabricated on the barrier layer.
