Patent ID: 7041529

Claim:
A method of fabricating a light-emitting device which comprises a transparent conductive semiconductor substrate, and a light-emitting layer portion composed of a compound semiconductor and bonded on one main surface of the transparent conductive semiconductor substrate while placing a substrate-bonding conductive oxide layer composed of a conductive oxide in between; and further comprises a contact layer for reducing junction resistance of the substrate-bonding conductive oxide layer, disposed between the light-emitting layer portion and the substrate-bonding conductive oxide layer so as to contact with the substrate-bonding conductive oxide layer; comprising: a light-emitting layer portion growth step for epitaxially growing the light-emitting layer portion composed of a compound semiconductor on a first main surface of a light-emitting-layer-growing substrate; a contact layer forming step for forming a layer for becoming the contact layer for reducing junction resistance with the substrate-bonding conductive oxide layer; a substrate-bonding conductive oxide layer forming step for forming the substrate-bonding conductive oxide layer on the bonding surface side of the light-emitting layer portion and/or the transparent conductive semiconductor substrate; a bonding step for bonding the light-emitting layer portion and the transparent conductive semiconductor substrate while placing the substrate-bonding conductive oxide layer in between, to thereby produce a substrate bond in which the layer for becoming the contact layer is disposed so as to contact with the substrate-bonding conductive oxide layer; and a separating step for separating the light-emitting-layer-growing substrate from the substrate bond.
