Patent ID: 6900068

Claim:
A method of forming a light emitting diode, comprising the steps of: providing a temporary semiconductor substrate having epi-layers thereon sequentially formed on a temporary substrate thereof with an n-type etch stop layer, a lower cladding layer, an active epi-layer, an upper cladding layer, and an ohmic contact epi-layer; forming a first ohmic contact metal electrode on said ohmic contact epi-layer; forming a mirror protective layer on said ohmic contact epi-layer and said first ohmic contact metal electrode; providing an electrically & thermally conductive substrate; bonding said electrically & thermally conductive substrate with said mirror protective layer by a metal adhesive layer in between; removing said temporary substrate and said n-type etch stop layer, etching sequentially from said lower cladding layer of foregoing resulted structure to expose a portion of ohmic contact epi-layer by a lithographic step and an etching step; forming a connection channel to expose a portion of said first ohmic contact metal electrode by etching said ohmic contact epi-layer through a lithographic step and an etching step; forming a second ohmic contact metal electrode on said lower cladding layer; and forming a bonding metal layer on said second ohmic contact metal electrode and on said ohmic contact epi layer and refilling said connection channel.
