A step-flow growth of a group-III nitride single crystal on a silicon single crystal substrate is promoted. A layer of oxide oriented to a &#x3c;111&#x3e; axis of silicon single crystal is formed on a surface of a silicon single crystal substrate, and group-III nitride single crystal is crystallized on a surface of the layer of oxide. Thereupon, a &#x3c;0001&#x3e; axis of the group-III nitride single crystal undergoing crystal growth is oriented to a c-axis of the oxide. When the silicon single crystal substrate is provided with a miscut angle, step-flow growth of the group-III nitride single crystal occurs. By deoxidizing a silicon oxide layer formed at an interface of the silicon single crystal and the oxide, orientation of the oxide is improved.
