Abstract
A vaporizing apparatus for providing a vaporized liquid precursor to a process chamber in a vapor deposition process includes a microdroplet forming device for generating microdroplets from a liquid precursor and a heated housing defining a vaporization zone having a vapor flow path from the microdroplet forming device to the process chamber. The vaporization zone receives the microdroplets and a heated carrier gas. The heated carrier gas has a temperature so as to provide the primary source of heat for vaporizing the microdroplets. A method of vaporizing liquids for vapor deposition processes includes generating microdroplets and utilizing a heated carrier gas as the primary source of heat for vaporizing the microdroplets. A vapor deposition system carrying out the method includes a heated carrier gas and a heated housing defining a heated vaporization zone. The heated housing receives the heated carrier gas. An atomizer for generating microdroplets from a liquid source dispenses the microdroplets in the heated vaporization zone. The heated carrier gas has a temperature so as to provide the primary source of heat for vaporizing the microdroplets in the vaporization zone. The vaporized liquid precursor is then directed to the process chamber from the heated vaporization zone.
