  • Publication number: 20090027996
    Abstract: Described is a mixing device and method for mixing fluids. Fluids to be mixed are introduced into a near-critical or a supercritical fluid carrier fluid. A density gradient is generated in the carrier fluid upon introduction of a fluid to be mixed that induces a convective velocity that provides for rapid mixing. The invention has application in such commercial applications as semiconductor and wafer fabrication where rapid cycle times or rapid mixing of fluids is required and where low tolerances for residues are permitted.

  • Patent number: 6780475
    Abstract: A method for depositing a substance on a substrate that involves forming a supercritical fluid solution of at least one supercritical fluid solvent and at least one solute, discharging the supercritical fluid solution through an orifice under conditions sufficient to form solid particles of the solute that are substantially free of the supercritical fluid solvent, and electrostatically depositing the solid solute particles onto the substrate. The solid solute particles may be charged to a first electric potential and then deposited onto the substrate to form a film. The solute particles may have a mean particle size of less than 1 micron.

  • Patent number: 6749902
    Abstract: A method for forming a continuous film on a substrate surface that involves depositing particles onto a substrate surface and contacting the particle-deposited substrate surface with a supercritical fluid under conditions sufficient for forming a continuous film from the deposited particles. The particles may have a mean particle size of less 1 micron. The method may be performed by providing a pressure vessel that can contain a compressible fluid. A particle-deposited substrate is provided in the pressure vessel and the compressible fluid is maintained at a supercritical or sub-critical state sufficient for forming a film from the deposited particles. The Tg of particles may be reduced by subjecting the particles to the methods detailed in the present disclosure.

  • Patent number: 6264726
    Abstract: The present invention is a method of separating a first compound having a macromolecular structure from a mixture. The first solvent is a fluid that is a gas at standard temperature and pressure and is at a density greater than a critical density of the fluid. A macromolecular structure containing a first compound is dissolved therein as a mixture. The mixture is contacted onto a selective barrier and the first solvent passed through the selective barrier thereby retaining the first compound, followed by recovering the first compound. By using a fluid that is a gas at standard temperature and pressure at a density greater than its critical density, separation without depressurization is fast and efficient.
