Following the first etch, the method includes performing, in the plasma chamber without removing the substrate from the chamber, an atomic layer passivation (ALP) process to deposit a conformal film of passivation over the mask and the features formed during the first etch. The ALP process uses a vapor from a liquid precursor to form passivation over the features and the mask. The method further includes performing, in the plasma chamber, a second etch of the material using the plasma etch process. The conformal film of passivation is configured to protect the mask and sidewalls of the features during the second etch. A plasma processing system also is described.

  • Patent number: 9257266
    Abstract: In a micro-channel plate, an electron emission film and an ion barrier film formed on a substrate are integrally formed by the same film formation step. In this structure, the electron emission film and the ion barrier film are made as continuous and firm films and the ion barrier film can be made thinner. Since the ion barrier film is formed on the back side of an organic film, the organic film is exposed during removal of the organic film. This prevents the organic film from remaining and thus suppresses degradation of performance of the ion barrier film due to the residual organic film, so as to suppress ion feedback from the micro-channel plate and achieve a sufficient improvement in life characteristics of an image intensifier.

The NMF does not interrupt the epitaxial growth of the RL and has little to no effect on the distribution of the RL c-axis orientation. The NMF increases the coercivity (Hc) and perpendicular magnetic anisotropy constant (Ku) of the RL.

The anode composition comprises an anode active material, a conductive material, and an acrylonitrile-acrylic acid copolymer with a high molecular weight as a binder. The acrylonitrile-acrylic acid copolymer has a molar ratio of acrylonitrile to acrylic acid of 1:0.01-2. Further provided are a method for preparing the anode composition and a lithium secondary battery using the anode composition. The binder has improved resistance to an electrolyte solution due to its enhanced adhesive strength. In addition, the use of the anode composition prevents the active material layer from being peeled off or separated from a current collector during charge and discharge to achieve improved capacity and cycle life characteristics of the battery.

  • Patent number: 8999183
    Abstract: A method involving ion milling is demonstrated to fabricate open-nanoshell suspensions and open-nanoshell monolayer structures. Ion milling technology allows the open-nanoshell geometry and upward orientation on substrates to be controlled. Substrates can be fabricated covered with stable and dense open-nanoshell monolayer structures, showing nanoaperture and nanotip geometry with upward orientation, that can be used as substrates for SERS-based biomolecule detection.

  • Publication number: 20150084726
    Abstract: An example variable reluctance device includes a load structure connected to an armature through a connecting arm. The armature is positioned between two oppositely oriented core structures. A structural frame secures the core structures in a fixed position, forming gap regions between the core structures and the armature, forming a magnetic circuit. The armature is resiliently centered between the core structures by a spring, such that the gaps and are approximately equal in width when the armature is at rest. The device further includes a magnetic substance within the gaps that is compressed or stretched to allow movement of the armature.

    Abstract: A method and composition for coating surfaces, a corresponding coating and the use of objects coated according to said method. A cleaned, metallic surface is contacted with an aqueous composition that is a dispersion or suspension, and drying and/or baking the organic coating or optionally, drying the organic coating and coating with an equivalent or additional coating composition prior to a drying and/or baking. The aqueous composition has a pH of 4 to 11 and contains an anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt. % relative to the total mass of the composition, which may have a solids content of from 2 to 40 wt. %. The solids have an average particle size from 10 to 1000 nm. A coating forms on the basis of an ionogenic gel which binds cations released from the metallic surface that originate from a pretreatment stage or from the contacting.
