Patent ID: 6853011

Claim:
A structure of light emitting diode, comprising: a transparent substrate; multi epi-layers, stacked sequentially from a bottom thereof,being with an upper cladding layer, an active layer epi-layer, a lower cladding layer; an ohmic contact epi-layer formed on said upper cladding layer; a first ohmic contact electrode metal layer formed on said ohmic contact epi-layer; a transparent bonding layer; the transparent substrate bonded on said first ohmic contact electrode metal layer by the transparent bonding layer; said multi epi-layers having a connection channel and a trench formed therein, wherein said connection channel is an electrical connection channel from said lower cladding layer punch-through said ohmic contact epi-layer so as to contact the first ohmic contact electrode metal layer and said trench is an isolated trench isolating at least said active layer into two parts; one part having said connection channel though it, the other part free connection channel; a second ohmic contact electrode metal layer formed on said lower cladding layer of said part of free said connection channel; a first bonding metal layer filled in connection channel; and a second bonding metal layer formed on said second ohmic contact electrode metal layer.
