    Abstract: PURPOSE: An AlGaInN substrate, an AlGalnN substrate washing method, an AlN substrate, and an AlN substrate washing method are provided to immerse the AlGaInN substrate into a washing solution while applying ultrasonic waves, thereby eliminating particles with a diameter of 0.2μm or greater existed on the surface of the AlGaInN substrate. CONSTITUTION: An AlGaInN substrate(45) is immersed in an acid solution(25). A photoelectron spectrum of the surface of the AlGaInN substrate is provided using an X-ray photoelectron spectroscopy with a detection angle of 10°. The acid solution is comprised of at least one kind of a group comprised of hydrofluoric acid, hydrochloric acid, and sulfuric acid. The AlGaInN substrate is immersed for 30 seconds or more. The concentration of the acid solution is 0.5 mass percent or greater.
