Abstract
A method for producing a gallium oxide semiconductor film by a mist CVD method, including, a mist-forming step in which a raw material solution containing gallium is misted in a mist-forming unit to generate mist, a carrier gas supply step of supplying a carrier gas for transferring the mist to the mist-forming unit, a transferring step of transferring the mist from the mist-forming unit to a film forming chamber using the carrier gas via a supply pipe connecting the mist-forming unit and the film forming chamber, a rectification step of rectifying flow of the mist and the carrier gas supplied to a surface of a substrate in the film forming chamber so as to flow along the surface of the substrate, a film forming step of heat-treating the rectified mist to form a film on the substrate, and an exhaust step of exhausting waste gas upward from the substrate.
