Beschreibung
Zusammenfassung:	A method of manufacturing a group III-nitride semiconductor includes a loading step, a pressure reduction step, a heating step, a first film forming step, and a second film forming step. In the pressure reduction step, a pressure in the chamber is reduced. In the heating step, the substrate is heated. In the first film forming step, an organic metal gas containing a group III element is supplied to the substrate in the chamber, and a first gas containing hydrogen gas and nitrogen gas is excited into plasma and supplied to the substrate in the chamber. In the second film forming step, an organic metal gas containing the group III element is supplied to the substrate in the chamber, and a second gas not containing hydrogen gas and containing nitrogen gas is excited into plasma and supplied to the substrate in the chamber.
