Patent ID: 7718450

Claim:
A method for manufacturing a nitride semiconductor device, wherein the nitride semiconductor device comprises a plurality of nitride semiconductor layers having an uppermost p-type nitride semiconductor layer in the plurality of nitride semiconductor layers, the method comprises the steps of: utilizing an MOCVD method to grow the plurality of nitride semiconductor layers including the uppermost p-type nitride semiconductor layer; irradiating a laser beam having a wavelength of 0.8 μm to 18 μm, which has an energy larger than a binding energy of Mg and H, on a surface of the p-type nitride semiconductor layer to activate the uppermost p-type nitride semiconductor layer, thereby separating off a bonding between the Mg and the H, wherein Mg is doped in the uppermost p-type nitride semiconductor layer and is an acceptor of the uppermost p-type nitride semiconductor layer and wherein H is absorbed by the uppermost p-type nitride semiconductor layer during growing the plurality of nitride semiconductor layer in MOCVD method; and dispersing the H that is separated from the p-type nitride semiconductor layer by carrying out a heat treatment at a temperature of between about 300 and about 400° C., to activate the acceptor.
