Abstract:
A method of manufacturing a compound semiconductor device having at least (1) a compound semiconductor layer grown by a vapor phase epitaxy (VPE) method and doped with p-type impurities, and formed of one gallium nitride-based semiconductor material selected from the group consisting of InxGa1âˆ’xN, AIxGa1âˆ’xN, AIxGayInzN, BxGa1âˆ’xN, and BxAIyGazN where 0&lE;Ã—&lE;1 in the case of a three-element mixed crystal compound, and x+y+z=1 in the case of four-element mixed crystal compound, and (2) an electrode, comprising activating the p-type compound semiconductor layer by irradiating UV waves that can be absorbed into the p-type impurity doped compound semiconductor layer, onto the p-type impurity doped compound semiconductor layer while annealing at a temperature of 350Â° C. to 500Â° C.
