Patent ID: 8283683

Claim:
A LED chip, comprising: a permanent substrate having a holding space on top of the permanent substrate; an insulating layer on top of the permanent substrate and covering the holding space; a first metal layer on top of the insulating layer; a second metal layer on top the insulating layer; a die comprising a eutectic layer and a light-emitting region, wherein the light-emitting region is on top of the eutectic layer, and the die is bonded to the first metal layer within the holding space via the eutectic layer coupling to the first metal layer; a filler structure filled between the die and the holding space; and a first electrode on top of the die, in contact with the light-emitting region and above the filler structure, and above and contacting the second metal layer, and the first electrode extending 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.
