  • Publication number: 20240347343
    Abstract: A technology is provided to form p-type regions and to effectively reduce a contact resistance between the p-type region and an electrode. One embodiment of a nitride semiconductor device manufacturing method may include a magnesium layer formation step of forming a magnesium layer that comprises magnesium as a major component on a surface of a nitride semiconductor substrate. The method may include an annealing step of annealing the nitride semiconductor substrate on which the magnesium layer is formed.
