Abstract

See full text

The present disclosure provides a method for producing a semiconductor element that can lower the potential risk of malfunction. The production method of the disclosure is a method for producing a semiconductor element which includes providing a semiconductor element precursor, the precursor having a metal electrode layer formed on the surface of a gallium oxide-based single crystal semiconductor layer and a dopant doped in at least part of an exposed portion on the surface of the gallium oxide-based single crystal semiconductor layer where the metal electrode layer is not layered, and annealing treatment of the semiconductor element precursor whereby the dopant is diffused to a portion of the gallium oxide-based single crystal semiconductor layer that are overlapping with the metal electrode layer in the layering direction, to form a Schottky junction between the gallium oxide-based single crystal semiconductor layer and the metal electrode layer.
