    Abstract: A reactor vessel is provided with a solvent in a supercritical PVT state for use in depositing films on a deposition substrate. A metal organic precursor is dissolved in the supercritical solvent, as is a reaction agent. A chemical reaction deposits a film, such as a metal film on a semiconducting wafer, and reaction byproducts including a ligand ensue from the chemical reaction. Effluent from the reactor vessel is submitted to a precursor-forming agent that reacts with the ligand to rejuvenate the precursor. Alternatively, the precursor-forming agent can be used for point-of-use formation of the precursor with or without recycle of reaction byproducts.

    Abstract: A system and method for performing hydrothermal treatment includes reactor vessel formed with a pressure bearing wall surrounding a reactor chamber. A liner protects the wall from exposure to temperature extremes, corrosives and salt deposits. The liner is formed with three layers: a non-porous, corrosion resistant primary layer; a porous layer; and a non-porous, secondary layer. The porous layer is sealed between the primary layer and the secondary layer. The liner is positioned in the reactor chamber with the secondary layer facing the pressure bearing wall of the reactor chamber and the primary layer facing the reactor chamber. Connectors extend through the wall of the reactor vessel and the secondary layer to allow a fluid to be pumped through the porous layer to maintain the temperature of the liner. The connectors also allow for sampling of the fluid within the porous layer to detect leaks in the primary layer.

    Abstract: Improved methods for conducting solid acid-catalyzed, near- or supercritical heterogeneous chemical reactions (e.g., alkylation reactions) are provided which give enhanced product yields and permit longer processing runs. The preferred reactions of the invention are carried out in the presence of a solid macroporous catalyst having a surface area of from about 50-400 m2/g and a pore size of from about 70-150 null. Product selectivity is enhanced by pressure-tuning of the reaction to promote production and separation of desired reaction products. In continuous processing, the chemical reaction may be interrupted before significant catalyst deactivation, followed by increasing reactor pressure and/or reducing reactor temperature to remove the accumulating coke; when the catalyst is regenerated, the original reaction conditions and reactant introduction may be resumed.

    Abstract: A method and apparatus for fabricating and drying wafers, including micro-electro-mechanical system (MEMS) structures, in a second, supercritical processing fluid environment. The apparatus utilizes an inverted pressure vessel connected to a supercritical processing fluid supply and recover system, with an internal heat exchanger connected to external heating and cooling sources, which is closed with a vertically movable base plate. A wafer cassette configured for supporting multiple wafers is submerged in a first processing fluid within a container, which is installed on the base plate for insertion into the pressure vessel. Vessel inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to nearly the base plate. Container inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to inside the container and nearly to the bottom of the container. The tubes provide for displacement of the first processing fluid with the second processing fluid still in a liquid state, from which it is raised to supercritical state.

    Abstract: For conversion of harmful compound in contaminated liquid into harmless compound by use of reactant, a plurality of agitators are arranged in a vertical superposition within a closed agitation chamber and, after the contaminated liquid is charged into the agitation chamber, the agitators are driven for rotation at a high speed in a rage from 10,000 to 18,000 rpm in order to create a field of super critical conditions in which free radicals are liberated from the harmful compound and coupled by the reactant. Neither high temperature heating nor high level pressurization is needed for processing of the contaminated liquid.

    Abstract: A reaction product is formed and transferred from an autoclave to a receiving vessel at a laminar flow rate, using a self-adjusting transfer mechanism. A specific amount of water in the receiving vessel is heated and vaporized prior to the reaction product transfer to raise the pressure in the receiving vessel to saturation pressure. A flow passage between the autoclave and the receiving vessel is now opened, and a resulting pressure differential between the autoclave and the receiving vessel initiates the transfer process. A heat exchanger cools the reaction product flowing from the autoclave to the receiving vessel, where the amount of cooling is dependent upon the transfer rate of the reaction product. An increased transfer rate will cause the hotter reaction product entering the receiving vessel to increase the pressure inside the receiving vessel, thereby reducing, or self-adjusting, the transfer rate. The heat exchanger may also generate steam which is fed into the receiving vessel to adjust the pressure in the receiving vessel and thus adjust the transfer rate of the reaction product.
