Patent ID: 8735196

Claim:
A method of manufacturing a nitride semiconductor light emitting device, comprising: forming a nitride semiconductor laminated body on a first substrate that has a first size; forming a first adhesion layer on the nitride semiconductor laminated body and a second adhesion layer on a second substrate, the first adhesion layer having a second size smaller than the first size; bonding the first substrate and the second substrate so as to generate a gap between the first substrate and the second substrate with the first adhesion layer and the second adhesion layer being in contact with each other; removing a portion of the first substrate mechanically so as to generate a recess having a third size equal to or larger than the second size; etching the first substrate while injecting a chemical solution into the recess until the nitride semiconductor laminated body is exposed; and etching the exposed nitride semiconductor laminated body using the chemical solution so as to form a concave-convex portion in the exposed nitride semiconductor laminated body.
