Abstract:
A method of fabricating a light emitting device in which a light emitting layer portion and a current spreading layer respectively composed of a Group III-V compound semiconductor, and an electrode for applying light emission drive voltage to the light emitting layer portion, are once stacked in this order on a single crystal substrate, the method comprising:a first vapor-phase growth step for forming the light emitting layer portion on the single crystal substrate by the metal organic vapor-phase epitaxy process; a second vapor-phase growth step, carried out after the light emitting layer portion was formed, for forming the p-type current spreading layer based on the hydride vapor-phase epitaxy process; and a high-concentration doped layer forming step for forming a high-concentration doped layer in a surficial area including the main surface on the electrode forming side of the current spreading layer, so as to have a carrier concentration of p-type dopant higher than that in the residual portion of the current spreading layer.
