Abstract
A light emitting epi-layer structure contains a temporary substrate of absorption light type on one side. The other side thereof is then adhered to a transparent substrate of light absorption free by BCB bonding layer. After that, the light absorption substrate portion is removed. The resulted light emitting structure is then patterned to form a connection channel to connect the first ohmic contact electrode and form an isolation trench to separate the active layer of the light emitting structure into two parts. Thereafter, a second ohmic contact electrode on the cladding layer and a bonding metal layer filled in the first channel and on second ohmic contact electrode are successively formed. The resulted LED structure is hence convenient for flip-chip package since two bonding metal layers have the same altitude.
