Patent ID: 7811838

Claim:
A method for manufacturing a high efficiency light-emitting diode, comprising: providing a growth substrate; forming an etching stop layer on the growth substrate; forming a first conductivity type ohmic contact layer on the etching stop layer; forming an illuminant epitaxial structure on a surface of the first conductivity type ohmic contact layer, wherein the illuminant epitaxial structure includes a first surface and a second surface on opposite sides, and the first surface of the illuminant epitaxial structure is directly connected with the surface of the first conductivity type ohmic contact layer; forming a second conductivity type compound electrode pad on a portion of the second surface of the illuminant epitaxial structure; providing a temporary substrate; bonding the temporary substrate to the illuminant epitaxial structure and the second conductivity type compound electrode pad by using a first bonding layer, wherein the first bonding layer is sandwiched in between the temporary substrate and the second surface of the illuminant epitaxial structure, and the first bonding layer comprises: a first protection layer; a second protection layer located between the first protection layer and the temporary substrate; and an adhesive layer located between the first protection layer and the second protection layer; removing the growth substrate to expose the etching stop layer; removing the etching stop layer to expose the first conductivity type ohmic contact layer; providing a permanent substrate; bonding the permanent substrate to the exposed first conductivity type ohmic contact layer by using a second bonding layer, wherein the second bonding layer is sandwiched in between the permanent substrate and the first conductivity type ohmic contact layer; and removing the temporary substrate and the first bonding layer.
