    摘要: The invention provides methods for concentrating a macromolecule from a solution comprising the macromolecule and an organic polymer by first subjecting the solution to ultrafiltration to produce a first retentate solution, then adjusting the conductivity of the first retentate solution such that any protein precipitation induced by the organic polymer is essentially prevented to produce a second retentate solution, and then subjecting the second retentate solution to ultrafiltration. In a preferred embodiment, the conductivity is adjusted by diafiltration against water, suitable diluent or buffer. Preferably, the invention pertains to the concentration of solutions of native or recombinant proteins. The invention further pertains preferably to methods for the concentration of cell culture supernatant comprising a product protein and organic polymers of the Pluronic family of block co-polymers, and more preferably comprising Pluronic F-68 block co-polymer.

    摘要: Embodiments of the invention generally provide etch or CVD plasma processing methods and apparatus used to generate a uniform plasma across the surface of a substrate by modulation pulsing the power delivered to a plurality of plasma controlling devices found in a plasma processing chamber. The plasma generated and/or sustained in the plasma processing chamber is created by the one or more plasma controlling devices that are used to control, generate, enhance, and/or shape the plasma during the plasma processing steps by use of energy delivered from a RF power source. Plasma controlling devices may include, for example, one or more coils (inductively coupled plasma), one or more electrodes (capacitively coupled plasma), and/or any other energy inputting device such as a microwave source.

    摘要: A plasma processing system for plasma processing of substrates such as semiconductor wafers. The system includes a plasma processing chamber, a substrate support for supporting a substrate within the processing chamber, a dielectric member having an interior surface facing the substrate support, the dielectric member forming a wall of the processing chamber, a gas supply comprising one or more injector tubes extending rectilinearly in the plasma processing chamber and having one or more orifices in a sidewall for supplying gas into the chamber, and an RF energy source such as a planar coil which inductively couples RF energy through the dielectric member and into the chamber to energize the process gas into a plasma state. The gas is supplied through orifices located outside of regions at the distal tip of the injector tubes where electric field lines are concentrated. The arrangement minimizes clogging of the orifices since the orifices are located away from areas where most build-up of process byproducts occur on the injector tube.

    摘要: An electrostatic chuck comprises an electrode cap with a dielectric layer for attracting and holding the back side of a semiconductor wafer positioned on the top surface of the dielectric layer, and a lower electrode. The electrostatic chuck is heated by resistive heating elements attached to or embedded within the chuck. The electrostatic chuck is cooled by circulating liquid coolant through the body of the chuck. Coolant gas is provided at the back side of the semiconductor wafer to improve thermal transfer. A feedback control mechanism maintains the chuck, and consequently the wafer, at a predetermined temperature by actively controlling both the heating and the cooling functions.

    摘要: An electrolyte membrane is disclosed, for use in a fuel cell, and is composed of ionic transporting elements embedded in a polymer matrix. The elements can be carbon products, dye stuffs molecules, organic molecules, inorganic molecules, semiconductors, oxides, or superconductors. The elements carry ionic groups by chemical attachment of physical absorption. The electrolyte membrane can be a homogeneous or inhomogeneous blend of the ionic transporting elements in the polymer matrix. An anode and an opposing cathode are on opposite sides of the membrane. Respective catalysts are on the anode and cathode. A gas diffusion layer contacts the anode and has openings to allow fuel from a fuel source to pass through to the anode, as fuel is consumed at the anode. Another gas diffusion layer contacts the cathode and has openings to allow oxygen to pass through to the cathode. Fuel consumption generates electricity and produces water.
