Patent ID: 8618562

Claim:
A light emitting device comprising: a multilayer body made of a semiconductor and including a light emitting layer, the multilayer body having a first surface and a second surface opposed to the first surface; a first bonding metal layer attached to the multilayer body; a substrate having a first surface and a second surface opposed to the first surface of the substrate; and a second bonding metal layer attached to the substrate and bonded to the first bonding metal layer at a bonding interface, a planar size of a region of the first surface of the multilayer body to which the first bonding metal layer is attached being smaller than a planar size of the first surface of the multilayer body, or a planar size of a region of the first surface of the substrate to which the second bonding metal layer is attached smaller than a planar size of the first surface of the substrate, the substrate being made of one of Si, SiC, GaAs, and GaP, and the first bonding metal layer being formed in order of Au, AuZn, and Au from the multilayer body side.
