摘要： The present disclosure relates to an apparatus and a method for forming a droplet aerosol for vaporization and subsequent thin film deposition on a substrate. The apparatus includes a mechanism to control the rate of liquid flow through the apparatus, the mechanism including a piezoelectric actuator to adjust the rate of liquid flow and an atomizing mechanism drawing gas from a compressed gas source 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 faun droplets suitable for vaporization and subsequent thin film deposition on a substrate.

摘要： An apparatus for controlling liquid flow wherein the apparatus comprises an orifice and an adjacent flexible diaphragm separated from each other by a gap through which a liquid flows. The diaphragm is sufficiently flexible to vary the gap thereby controlling the rate of liquid flowing through the orifice or to provide a positive liquid shutoff of liquid flowing through the orifice. A method for controlling liquid flow through the apparatus comprises flexing said diaphragm to vary a size of the gap to control the rate of liquid flowing through the orifice or to provide a positive liquid shutoff of liquid from flowing through the orifice.
