Abstract
The disclosure provides a film forming method that enables to obtain an epitaxial film with reduced defects such as dislocations due to a reduced facet growth industrially advantageously, even if the epitaxial film has a corundum structure. When forming an epitaxial film on a crystal-growth surface of a corundum-structured crystal substrate directly or via another layer, using the crystal substrate having an uneven portion on the crystal-growth surface of the crystal substrate, generating and floating atomized droplets by atomizing a raw material solution including a metal; carrying the floated atomized droplets onto a surface of the crystal substrate by using a carrier gas; and causing a thermal reaction of the atomized droplets in a condition of a supply rate limiting state.
