Abstract: A method for manufacturing a p-type gallium nitride-based (GaN) device is disclosed. In accordance with the method, an Mg in an MgNx layer disposed on p-type gallium nitride is diffused into the p-type gallium nitride by a heat treatment to dope the p-type gallium nitride with the Mg while activating the diffused Mg simultaneously, eliminating a need for an additional heat treatment for the activation and preventing a nitrogen in the p-type gallium nitride from being separated therefrom.
