摘要： A method and apparatus are disclosed for exposing particles in a gas in order to cause the charge on the particles to change, the apparatus comprising a chamber having a conductive wall with a gas inlet and a gas outlet. An electrode with an exposed tip is in the chamber, the electrode being held at a different potential from the ground potential. The electrode is connected to a source of voltage sufficient to cause a corona discharge to occur forming ions in the chamber, and creating a region with a high electric field intensity and another region in which the electric field intensity is lower. The inlet and outlet define a gas flow path from the inlet to the outlet such that the gas flow path passes mainly through the region with the lower electric field intensity.

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.

摘要： A method for vaporizing a liquid for subsequent thin film deposition on a substrate. The method comprises vaporizing a liquid which is disposed within a tubular porous metal body. The porous metal body comprises a first surface defining a first carrier gas flow path and a second surface defining a second carrier gas flow path in a substantially opposite direct to the first carrier flow path. Vapor is generated from the liquid and added to a carrier gas that passes sequentially in direct contact along the first and second surfaces of the porous metal body to form a gas/vapor mixture with the carrier gas first flowing along the first surface and then along the second surface thereby providing a gas/vapor mixture for thin film deposition.

摘要： An apparatus for atomizing a precursor liquid for vapor generation and thin film deposition on a substrate. The precursor liquid is atomized by a carrier gas to form a droplet aerosol composed of small precursor liquid droplets suspended in the carrier gas. The droplet aerosol is then heated to form vapor, producing a gas/vapor mixture that can be introduced into a deposition chamber to form thin films on a substrate. The liquid is introduced into the atomizing apparatus in such a manner as to avoid excessive heating that can occur or lead to the formation of undesirable by-products due to material degradation as result of thermal decomposition. The apparatus is particularly suited for vaporizing high molecular weight substances with a low vapor pressure that requires a high vaporization temperature for the liquid to vaporize. The apparatus can also be used to vaporize solid precursors dissolved in a solvent for vaporization.

摘要： A condensation nucleus counter has a series of flow passageways forming a flow path, including a first passageway for carrying the gas stream having the particles to be detected which is preferably preheated A saturator is positioned to receive the flow of the gas stream and is made of a porous material of a controlled pore size having a portion immersed in a liquid working fluid. The liquid working fluid moves by capillary action along the length of the saturator. Vapor from the working liquid will be transferred to the gas stream as it moves through the saturator. The gas stream then passes to a condenser that reduces the temperature of the gas stream and causes the working fluid vapor to condense on the particles in the gas stream to form droplets that can be detected and counted.
