Abstract:
Disclosed is a method of fabricating a gallium nitride substrate using a plurality of ion implantation processes. A method of fabricating a gallium nitride substrate using a plurality of ion implantation processes according to an embodiment of the present disclosure includes a step of forming a bonding oxide film on the first gallium nitride; a step of performing first ion implantation for a surface of the first gallium nitride, on which the bonding oxide film is formed, at least once to form a damaged layer, thereby releasing bowing of the first gallium nitride; a step of performing second ion implantation for the surface of the first gallium nitride, on which the bonding oxide film is formed, to form a blister layer; a step of bonding the bonding oxide film of the first gallium nitride to a temporary substrate; a step of separating the first gallium nitride using the blister layer to form a seed layer; and a step of allowing growth of the second gallium nitride using the seed layer to form bulk gallium nitride.

Claim (Index 14):
The method according to  claim 1 , wherein the temporary substrate is at least one of sapphire, gallium arsenide (GaAs), spinel, silicon (Si), indium phosphide (InP), and silicon carbide (SiC).
