Abstract
A laminate including: a crystal substrate; and a semiconductor film provided on a main surface of the crystal substrate, the semiconductor film being mainly made of an oxide semiconductor containing a dopant and having a corundum structure, where the oxide semiconductor has a silicon concentration of 5.0×10cmor less, and the semiconductor film has a resistivity of 150 mΩ·cm or less. This provides a laminate including a semiconductor having low resistance and a corundum structure suitable for use in semiconductor devices.
