Abstract:
A method of manufacturing a Group III-V compound semiconductor which contains Group II elements as p-type impurities and which is expressed by a general formula InxGayAlzN (0&lE;x&lE;1, 0&lE;y&lE;1, 0&lE;z&lE;1, x+y+z=1) which comprises conducting thermal decomposition by a vapor phase method using metalorganics, wherein the carrier gas is an inert gas in which the concentration of hydrogen is 0.5% or smaller by volume, and the concentration of hydrogen is maintained at 0.5% or smaller by volume in an atmosphere, during a reduction in temperature of the Group III-V compound semiconductor after the Group III-V compound semiconductor is grown.
