ABSTRACT:
A first buffer layer is formed on a substrate at a lower temperature than a single-crystal-growth-temperature, one or more of a layer composed of a nitride containing neither Ga nor In, a layer which has two or more thin films having different moduli of elasticity cyclically laminated therein, and a layer having an Al composition ratio which decreases and a Ga composition ratio which increases in a direction from the first buffer layer to a device-constituting layer are formed as a second buffer layer on the first buffer layer at the single-crystal-growth-temperature, and a device-constituting layer composed of a nitride semiconductor is formed on the second buffer layer.
