Abstract: The present disclosure relates to an apparatus 10 and a method for forming a droplet aerosol for vaporization and subsequent thin film deposition on a substrate. The apparatus 10 includes a mechanism to control the rate of liquid flow through the apparatus 10, the mechanism including a piezoelectric actuator 240 to adjust the rate of liquid flow and an atomizing mechanism drawing gas from a compressed gas source 70 such that when the gas source conjoins with the liquid, the liquid is atomized to form droplets suspended in the gas thereby forming a droplet aerosol suitable for subsequent thin film deposition on a substrate. The method includes drawing a gas from a compressed gas source and drawing a liquid from a liquid source. The liquid and gas are conjoined in either a coaxial flow relationship or a radial flow relationship or an angular relationship between radial and coaxial flow wherein the gas engages the liquid to form droplets suitable for vaporization and subsequent thin film deposition on a substrate.

Abstract: The present invention involves injecting a liquid and gas into a vapor holding chamber (30) held at a sufficiently high temperature to insure all the liquid injected is vaporize and held in the chamber (30) as a vapor. The gas/vapor mixture is then delivered to the deposition chamber (70) in which the deposition substrate (72) is held.

Abstract: An apparatus and method for generating vapor from a liquid precursor for a thin film deposition on a substrate includes an inlet 130 section in fluid communication with a downstream vaporization chamber 120 section. The inlet 130 section comprises a gas inlet for receiving gas from a gas source 180 through a gas flow sensor 202 and a gas flow control valve 230 and a liquid inlet 150 for receiving liquid from a liquid source 220 through a liquid flow sensor 210 and a liquid flow control valve 230. An electronic controller 600 controls the gas and liquid flow control valves 230 thereby controlling the rates of gas and liquid flow into the inlet 130 section to generate vapor in the downstream vaporization chamber 120 section for thin film deposition on the substrate.

Abstract: A vaporization system (50, 92, 92a, 92b, 180) for thin film formation and for introducing vapors into a deposition chamber (26, 84, 130) for depositing films onto a semi-conductor surface has a vaporization chamber (52, 116, 192) that is selectively provided with at least two different, that is selectively provided with at least two different, separate, precursor liquids (54A, 54B, 54C, 110A, 110B, 186) carried in a gas stream that may be a single carrier gas, or a selected one of a plurality of carrier gases from gas sources (12, 62A, 62B, 62C, 98A, 98B, 184). When the liquids being introduced are likely to be subject to thermal decomposition from contact with high temperature surfaces, an atomizer (94, 142A, 142B, 154A, 154B, 182) is used at the inlet of the vaporization chamber (52, 116, 192) to provide an aerosol to the vaporization chamber (52, 116, 192) from one or more individual carrier gases from gas sources 12, 62A, 62B, 62C, 98A, 98B for simultaneous or sequential introduction into the vaporization chamber (52, 116, 192). The vaporization chamber (52, 116, 192) may be designed to insure complete vaporization by incorporating a recirculating gas flow through heated passageways (198, 124, 202, 212) before the vaporized gas/vapor mixture exits the vaporization chamber (52, 116, 192).
