Abstract
A method for producing a light-emitting device, includes: performing, on a first substrate made of III-V group compound semiconductor, crystal growth of a laminated body including an etching easy layer contiguous to the first substrate and a light-emitting layer made of nitride semiconductor; bonding a second substrate and the laminated body; and detaching the second substrate provided with the light-emitting layer from the first substrate by, one of removing the etching easy layer by using a solution etching method, and removing the first substrate and the etching easy layer by using mechanical polishing method.
Claims9
A light-emitting device comprising:
- a first laminated body in which, a laminated body made of III-V group compound semiconductor containing a light-emitting layer, a conductive transparent electrode, and a first metal layer, are sequentially provided;
- and
- a second laminated body having a semiconductor substrate and a second metal layer provided on the semiconductor substrate,
- the first metal layer and the second metal layer being bonded, and
- a radiant light from the light-emitting layer passing through the transparent electrode, being reflected by the first metal layer, and being taken out to the outside.
