Patent ID: 8592234

Claim:
A method for manufacturing a LED, comprising steps of: providing a temporary substrate; forming a light-emitting region on the surface of the temporary substrate; forming at least an eutectic layer above a first surface of the light-emitting region; cutting the resulting structure into a plurality of dies, wherein a first die of the dies includes a portion of the temporary substrate, a portion of the light-emitting region, and a portion of the eutectic layer; providing a permanent substrate having a holding space on top of the permanent substrate; forming an insulating layer on to of the permanent substrate and covering the holding space; forming a first metal layer on to of the insulating layer; forming a second metal layer on to of the insulating layer; bonding the first die to the first metal layer within the holding space via the eutectic layer coupling to the first metal layer; forming a filler structure filled between the first die and the holding space; removing the temporary substrate of the first die; and forming a first electrode on to of the first die, in contact with the light-emitting region and above the filler structure, and above and contacting the second metal layer, wherein the first electrode is extended to outside of the holding space; wherein a portion of a surface of the light-emitting region is exposed from the filler structure and the first electrode, and the second metal layer is formed between the first electrode and the insulating layer.
