  • Patent number: 8916232
    Abstract: The embodiments fill the need of improving electromigration and reducing stress-induced voids of copper interconnect by enabling deposition of a thin and conformal barrier layer, and a copper layer in the copper interconnect. The adhesion between the barrier layer and the copper layer can be improved by making the barrier layer metal-rich prior copper deposition and by limiting the amount of oxygen the barrier layer is exposed prior to copper deposition. Alternatively, a functionalization layer can be deposited over the barrier layer to enable the copper layer being deposit in the copper interconnect with good adhesion between the barrier layer and the copper layer. An exemplary method of preparing a substrate surface of a substrate to deposit a functionalization layer over a metallic barrier layer of a copper interconnect to assist deposition of a copper layer in the copper interconnect in an integrated system in order to improve electromigration performance of the copper interconnect is provided.

    Abstract: A method to fabricate a hierarchical graduated-branched structure that grows in a three-dimensional pattern down to fractal-branching, nano-size level is detailed. The fractal patterning is accomplished on a three-dimensional (i.e., non-planar) surface, by exposing the surface to a properly focused particle beam, which causes the spontaneous growth of graduated branches all over the surface. The structure can be fabricated with a single material and the fractal-patterning is done in a one step process. No addition of material is required for the formation of each branch. The fractal graduated branching structure can then be molded in order to produce replicas.

The glass surface is first treated by any suitable method to enhance the ability of a chitosan polymer coating to durably or substantially permanently adhere thereto. Once the chitosan coating has been applied to the glass surface, the normally hydrophilic chitosan coating is rendered hydrophobic by suitable treatment, for example, by a combination of enzymatic and chemical treatments. Alternatively, the chitosan may be rendered hydrophobic prior to coating it on the glass surface, but that is a less preferred technique.

  • Publication number: 20140147627
    Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressures (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.

  • Patent number: 8709542
    Abstract: This invention relates to a method for preparing an organic film at the surface of a solid support, with a step of contacting said surface with a liquid solution including (i) at least one protic solvent, (ii) at least one adhesion primer, under non-electrochemical conditions, and allowing the formation of radical entities based on the adhesion primer. The liquid solution can also include (iii) at least one monomer different from the adhesion primer and radically polymerizable. This invention also relates to a non-electrically-conductive solid support on which an organic film according to said method is grafted, and a kit for preparing an essentially polymeric organic film at the surface of a solid support.

  • Patent number: 8647699
    Abstract: The invention relates to a process for producing biomedical articles, in particular, silicone hydrogel contact lenses having durable hydrophilic chitosan coating. The chitosan coating is covalently attached to the medical device by performing a crosslinking reaction between chitosan and the carboxylic groups on the surface of a medical device directly in a sealed package during autoclave. The coated biomedical articles obtainable by the process of the invention have desirable characteristics regarding adherence to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus especially useful in the field of ophthalmic devices.

  • Patent number: 8642117
    Abstract: A liquid composition for forming an activator-containing layer on a substrate, for activating a chemical reaction to produce a solid layer on the substrate, comprises activator, surfactant and solvent and/or binder. The liquid composition is deposited on a surface of a substrate, desirably by inkjet printing. The layer is used to activate a chemical reaction to produce a solid layer on the substrate surface, e.g. a layer of conductive metal. The surfactant in the liquid composition has beneficial effects on the behavior of the liquid composition when applied to certain substrates.

  • Patent number: 8628831
    Abstract: The present invention relates to the field of selective metallization, and in particular to preparing a polymer article for selective metallization by submerging the article in a first liquid, and while submerged irradiate the article by a laser beam the area of the article on which the metal is to be deposited. An activation step, prior to the selective metallization, comprises submerging the article in an activation liquid for depositing seed particles in the selected area. The irradiation of the selected area is proportionate so as to cause a temporary melting of the polymer in the surface of the selected area of the polymer article. The invention is advantageous in that the preparation may be performed with a relatively high scan rate across the polymer article, and in that a quite limited use of toxic chemicals.

  • Publication number: 20140004266
    Abstract: A method for electroless coating of a substrate by applying an activating coat of polyelectrolyte or salt with a first aqueous composition, rinsing of the activating coat such that the activating coat is not entirely removed The activated surface that has remained after rinsing is then contacted with an aqueous composition in the form of a solution, emulsion or suspension to form an organic secondary coat (precipitation coat), and drying. The activating coat contains at least one cationic polyelectrolyte or at least one cationic salt in solution in water. The aqueous composition which forms the secondary coat contains constituents which can be precipitated, deposited and/or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, which is made of the activating coat and the secondary coat, has a thickness of at least 1 ?m.

  • Patent number: 8586143
    Abstract: The present invention relates to a method of grafting, by covalent bonding, hollow or solid composite capsules onto any type of natural, artificial or synthetic, organic or inorganic, support, the capsules being chemically, physically or physico-chemically modified, so as possibly to improve their affinity with the support and to functionalize them, and then grafted, after the capsules and/or the support have been activated. The invention also relates to the capsules thus modified, to the supports grafted by the capsules, especially fibres and textiles, and also to the use of these grafted supports, especially fibres and textiles, for making up what are called “functional” articles.
