Abstract: PURPOSE: A method for manufacturing a nitride semiconductor substrate is provided to be capable of reducing manufacturing costs and increasing the area. CONSTITUTION: A buffer layer(11) made of an aluminum nitride(AlN) film is formed on a silicon substrate(10) for buffering lattice mismatch by using MBE(Molecular Bean Epitaxy). An oxide layer(11a) is formed on the buffer layer(11) by performing thermal oxidation processing. A nitride layer(12) is formed on the oxide layer(11a). Then, the silicon substrate(10) is removed.
