Abstract: A method, apparatus and system for minimizing a quantity of particulate matter entrained within a gas stream is provided. A coarse filter removes at least a portion of particulate matter having a relatively-large particle size from the gas stream. An agglomerator agglomerates particulate matter having a relatively-small particle size remaining in the gas stream into particulate clusters after the portion of the particulate matter having the relatively-large particle size has been removed by the coarse filter. An injector introduces an agglomerating material into the gas stream before the gas stream enters the agglomerator. The agglomerating material promotes agglomeration of the particulate matter having the relatively-small particle size into the particulate clusters. And a second filter receives the gas stream and removes at least a portion of the particulate clusters entrained within the gas stream exiting the agglomerator.

Abstract: 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.
