  • Publication number: 20100068489
    Abstract: The carbon-doped metal oxide films described provide a low coefficient of friction, typically ranging from about 0.05 to about 0.4. Applied over a silicon substrate, for example, the carbon-doped metal oxide films provide anti-stiction properties, where the measured work of adhesion for a coated MEMS cantilever beam is less than 10 ?J/m2. The films provide unexpectedly low water vapor transmission. In addition, the carbon-doped metal oxide films are excellent when used as a surface release coating for nanoimprint lithography. The carbon content in the carbon-doped metal oxide films ranges from about 5 atomic % to about 20 atomic %.

  • Publication number: 20100035163
    Abstract: Embodiments of the invention relate to methods useful in the fabrication of nanostructured devices for optics, energy generation, displays, consumer electronics, life sciences and medicine, construction and decoration. Instead of nanostructuring using colloids of particles, special vacuum deposition methods, laser interference systems (holography), and other low-throughput limited surface area techniques, we suggest to use nanotemplate created by novel nanolithography method, “Rolling mask” lithography. This method allows fast and inexpensive fabrication of nanostructures on large areas of substrate materials in conveyor-type continuous process. Such nanotemplate is then used for selective deposition of functional materials. One of embodiments explains deposition of functional materials in the exposed and developed areas of the substrate. Another embodiment uses selective deposition of the functional material on top of such template.

  • Patent number: 7638167
    Abstract: We have developed an improved vapor-phase deposition method and apparatus for the application of films/coatings on substrates. The method provides for the addition of a precise amount of each of the reactants to be consumed in a single reaction step of the coating formation process. In addition to the control over the amount of reactants added to the process chamber, the present invention requires precise control over the total pressure (which is less than atmospheric pressure) in the process chamber, the partial vapor pressure of each vaporous component present in the process chamber, the substrate temperature, and typically the temperature of a major processing surface within said process chamber. Control over this combination of variables determines a number of the characteristics of a film/coating or multi-layered film/coating formed using the method. By varying these process parameters, the roughness and the thickness of the films/coatings produced can be controlled.

  • Publication number: 20090305513
    Abstract: Embodiments of the invention relate to a method of functional materials deposition using a polymer template fabricated on a substrate. Such template forms an exposed and masked areas of the substrate material, and can be fabricated using polymer resists or Self-assembled monolayers. Deposition is performed using an applicator, which is fabricated in the shape of cylinder or cone made of soft elastomeric materials or laminated with soft elastomeric film. Functional materials, for example, metals, semiconductors, sol-gels, colloids of particles are deposited on the surface of applicator using liquid immersion, soaking, contact with wetted surfaces, vapor deposition or other techniques. Then wetted applicator is contacted the surface of the polymer template and rolled over it's surface. During this dynamic contact functional material is transferred selectively to the areas of the template. Patterning of functional material is achieved by lift-off of polymeric template after deposition.

  • Publication number: 20090297989
    Abstract: Embodiments of the invention relate to methods and apparatus useful in the nanopatterning of rotationally symmetric disk materials, like magnetic and optical disks, where a rotatable mask is used to image a radiation-sensitive material. Typically the rotatable mask comprises a cone. The nanopatterning technique makes use of Near-Field photolithography, where the mask used to pattern the disk is in contact or close proximity with the disk. The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a rotating cone surface comprises metal nano holes or nanoparticles.

    Abstract: Embodiments of the invention relate to lithography method useful for patterning at sub-micron resolution. This method comprised of deposition and patterning self-assembled monolayer resists using rolling applicator and rolling mask exposure apparatus. Typically the application of these self-assembled monolayers involves contacting substrate materials with a rotatable applicator in the shape of cylinder or cone wetted with precursor materials. The nanopatterning technique makes use of Near-Field photolithography, where the mask used to pattern the substrate is in contact with self-assembled monolayer. The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a rotating mask surface comprises metal nano holes or nanoparticles.

  • Publication number: 20080312356
    Abstract: A method of providing a biocompatible PEG-comprising coating on a substrate, without the use of an underlying adhesion layer. The coating is vapor deposited onto the substrate from a precursor which includes a PEG-derived moiety and an amino silane-containing functional group which reacts with the substrate. The substrate may be metal or plastic, where plastic excludes polyimide and polycarbonate. The substrate may be plasma treated prior to deposition of the PEG-comprising coating.

  • Publication number: 20080274281
    Abstract: We have developed an improved vapor-phase deposition method and apparatus for the attachment of organic films/coatings containing a variety of functional groups on halogen-containing substrates. The substrate surface is halogenated using a vaporous halogen-containing compound, followed by a reaction with at least one organic molecule containing at least one nucleophilic functional group. Halogenation of the substrate surface and subsequent reaction with the organic molecule are carried out in the same process chamber in a manner such that the halogenated substrate surface does not lose its functionality prior to reaction with the nucleophilic functional group(s) on the organic molecule.

  • Publication number: 20080083329
    Abstract: We have devised an apparatus useful for and a method of removing impurities from vaporous precursor compositions used to generate reactive precursor vapors from which thin films/layers are formed under sub-atmospheric conditions. The method is particularly useful when the layer deposition apparatus provides for precise addition of quantities of different combinations of reactants during a single step or when there are a number of different individual steps in the layer formation process, where the presence of impurities has a significant affect on both the quantity of reactants being charged and the overall composition of the reactant mixture from which the layer is deposited. The method is particularly useful when the vapor pressure of a liquid reactive precursor is less than about 250 Torr at atmospheric pressure.

  • Publication number: 20080081151
    Abstract: An improved vapor-phase deposition method and apparatus for the application of multilayered films/coatings on substrates is described. The method is used to deposit multilayered coatings where the thickness of an oxide-based layer in direct contact with a substrate is controlled as a function of the chemical composition of the substrate, whereby a subsequently deposited layer bonds better to the oxide-based layer. The improved method is used to deposit multilayered coatings where an oxide-based layer is deposited directly over a substrate and a SAM organic-based layer is directly deposited over the oxide-based layer. Typically a series of alternating layers of oxide-based layer and organic-based layer are applied.
