Patent ID: 7763486

Claim:
A method for manufacturing a nitride semiconductor stacked structure, comprising: mounting a substrate in a reaction furnace, feeding into the reaction furnace a compound including a Group V element and raising temperature of the substrate to within a range from higher than 900° C. to lower than 1200° C.; forming a p-type nitride semiconductor layer on the substrate at the substrate temperature by feeding into the reaction furnace an organometallic compound including a Group III element, compounds including a Group V element and including ammonia and a hydrazine derivative, and a p-type impurity source material at respective molar flow rates, wherein molar flow ratio of the hydrazine derivative to the organometallic compound including a Group III element is within a range from 1 to smaller than 25, and molar flow ratio of the ammonia to the hydrazine derivative is within a range from 10 to smaller than 500, and nitrogen and hydrogen as carrier gases at a predetermined compositional ratio by volume, so that the p-type nitride semiconductor layer has a relatively low resistivity, as formed, and without being thermally treated; and cooling the substrate to room temperature after stopping the feeds of the organometallic compound including a Group III element and the p-type impurity material.
