Abstract:
A method of manufacturing a gate switching device is provided. The method includes: forming an oxide insulating layer on a gallium nitride semiconductor layer of n-type or i-type; forming a gallium oxide layer at an interface between the oxide insulating layer and the gallium nitride semiconductor layer by heating the oxide insulating layer and the gallium nitride semiconductor layer at a temperature higher than a temperature of the oxide insulating layer and the gallium nitride semiconductor layer in the formation of the oxide insulating layer; and forming a gate electrode opposed to the gallium nitride semiconductor layer via the gallium oxide layer.

Claim (Index 2):
The method of  claim 1 , wherein\n the oxide insulating layer has a characteristic by which oxygen atoms are discharged from the oxide insulating layer and oxygen vacancies are generated in the oxide insulating layer when the oxide insulating layer is heated, and a relationship of E V0 \u22122(E 2 \u2212E 1 )<3.6 eV is satisfied, where E v0  is energy required to discharge one oxygen atom from the oxide insulating layer, E 1  is an energy level of an unoccupied state generated by the oxygen vacancies, and B 2  is a Fermi level of the gallium nitride semiconductor layer.
