Patent ID: 7960745

Claim:
A light emitting device, comprising a bonding object layer provided with a light emitting layer section, composed of Group III-V compound semiconductor, having a double heterostructure of an n-type cladding layer, an active layer and a p-type cladding layer, each composed of AlGaInP having composition lattice-matched with GaAs, stacked in this order, set to have a first main surface side as p type and a second main surface side as n type, having a light extraction side electrode formed to cover the first main surface partially, and a structure that an n-type transparent device substrate, composed of Group III-V compound semiconductor having greater band gap energy than the active layer, is bonded to the second main surface of the bonding object layer, wherein on one sides of the transparent device substrate and the bonding object layer, bonding surfaces to the other are formed, and an InGaP intermediate layer, comprising a high concentration Si doping layer having concentrated Si as an n-type dopant formed on the bonding surface side, is formed.
